Global Condition Monitoring Solution for High Voltage Cable Systems

LIOS in cooperation with its partner TechImp provide the world’s first combined Distributed Temperature Sensing (DTS) equipment together with Partial Discharge (PD) solutions to the power industry.  This complemented combination of DTS and PD solutions provides grid owners an even better control and monitoring possibility of their grids.
Together with Real Time Thermal Rating (RTTR), a platform has been created for a complete scope of condition assessment, control, monitoring and ampacity predictions.

The Global Condition Monitoring approach allows most of the failure modes of apparatus and electrical assets to be diagnosed, thus increasing reliability and decreasing maintenance costs, thanks to phenomena correlation.

• Diagnostics allows failure uncertainty to be reduced.
  • Optimization of the maintenance procedures
  • Condition Based Maintenance
• Maximization of the system components availability.

The crucial benefit of this cooperation between two leading suppliers to the T&D market is characterised by the innovative concept of Global Condition Monitoring, based on general purpose platforms, supporting different sensors (PD, DGA, DTS, Tan-delta and Vibrations) through a unique system integrating diagnostic algorithms upon data coming from these sensors. Therefore an overall reinforcement of the diagnostic effectiveness and robustness of the diagnostic power is obtained, but at a lower cost.

Such a superior diagnostic power is achieved by advanced tools, formerly developed for PD, based on TechImp’s unique SID (Separation, Identification, Diagnosis) strategy, which allows noise rejection, PD source separation and identification. TechImp patented technology provides a powerful and efficient diagnostic approach able to disentangle even the most critical PD phenomena, thus improving PD identification from different overlapping PD and noise sources.

TechImp PD separation technology allows different Partial Discharge phenomena to be classified on the basis of their pulse shape and split in different clusters (TF map®), so that further analysis can be carried out on each dataset, separately. This enhances the likelihood of PD source identification, even for non skilled operators.

Now this technologies have been extended to integrate novel sensors and data, adding integrated diagnostic levels based on fuzzy logic and artificial intelligence techniques for a cross-correlation on the whole set of data, giving a better and global coverage of possible faults, comprising, electrical, chemical/physical, mechanical degradation of the monitored electrical asset.

De facto standard for seamless DTS integration: Direct link to SCADA

The intrinsic temperature measuring system DTS based on LIOS Technology’s design, with fibre optic sensors either installed within the power cable’s cross section (FIMT – Fibre in metal tube ) or attached to the exterior of the cable, makes it possible to record the temperature profile along an entire cable route continuously, and to pinpoint the exact location of hot spots within a metre.

Most commonly the measured temperature profile data is transmitted via standard interfaces from systems of the DTS as required, and be either displayed or further processed by PC, PLC or SCADA systems. As a result of the increasing demands placed on the ability to network and integrate measuring systems into management systems, LIOS offers network components that summarise DTS data from several DTS units and transport or convert it to the required network standards and protocols like Modbus, DNP3, IEC60870-5 or XML based data interfaces (e.g. POSC).

Equipped with the Embedded Communication Module (ECM) the Distributed Temperature Sensing (DTS) evaluation unit is accessible by Ethernet/ LAN, holds its own IP address and is compatible with DHCP.
The on-board storage facility of measurement data provides automatic buffering of network break downs. It can handle multiple protocols, so the DTS can be directly linked to PLC or SCADA systems and communicates in various industrial protocol standards providing measured data and customised alarm information.
Hereby, the evaluation unit communicates as a TCP /IP server with several clients.

Features of the embedded communication module of the LIOS DTS controller:

• Configuration and operation of the DTS via two independent channels:
  • RS232
  • Ethernet TCP/IP
• Onboard storage of measurement data
  • Buffers up to 72 hours of measurement data and initiates data transfer automatically after communication link was re-established
  • Individual file access to measurement data through CHARON_02 (onboard data storage 1 GB)
• Allows to operate individual Plug-In-Interfaces for customer specific protocol solutions
  • The DTS can communicate in parallel with its proprietary protocol and one or more customer specific protocols like DNP3, IEC60870-5-104, IEC61850, POSC WITSML, Modbus (Master/Slave) etc.
  • Individual assignments for protocols and client addresses (IP) possible
• Ethernet communication to and from clients with high bandwidth
• Module comes with built-in user configurable Firewall and enables reliable operation even in WAN’s
• Secure data transmission and individual authorisation according TLS- Standard (RFC 2246)

The most common industrial protocols used in electrical systems worldwide are introduced in the following section. However, also other protocol standards are available or can be implemented for the ECM. Please contact us in case of questions.

MODBUS
The MODBUS protocol was published by Modicon in 1979. It is a quite simple single master – multiple slave protocol widely used in general purpose SCADA applications. It provides binary (bit) and 16-bit integer data, but no floating point values, polled by the master, i.e. the slave cannot send data spontaneously. The protocol specification is openly published and royalty-free. In the DTS ECM, TCP/IP is used as transport layer.

IEC 60870-5
IEC 60870-5 provides a communication profile for sending basic Telecontrol messages between systems. It was developed by the IEC Technical Committee 57 (Working Group 03) as a protocol standard for Telecontrol, Teleprotection, and associated telecommunications for electric power systems. The result of this work is IEC 60870-5. The protocol provides inter alia bit, integer and floating point data with or without time stamps. Data is transmitted from controlled stations (slaves) either by polling or spontaneously. In the ECM the IEC 60870-5-104 companion standard, defining standard TCP/IP connections as transport layer, is used.

DNP3
DNP3 (Distributed Networking Protocol) is an open standard managed by the DNP User Group. Initially; the DNP3 protocol was developed by Westronic (now GE-Harris) in 1993. It is widely used in electrical systems worldwide, including North and South America, the UK, Southeast Asia, South Africa, Australia, and New Zealand. It has gained wider use beyond electrical utilities, e.g. for water supply as well. The DNP3 protocol is also referenced in IEEE Std. 1379-2000, which recommends a set of best practices for implementing modern SCADA Master-RTU/IED communication links.
The protocol provides bit, integer and floating point data and time stamps. Data is transmitted from the outstation (slave) either by polling or spontaneously. The ECM uses TCP/IP as transport layer, but even in this mode the DNP3 protocol additionally uses its own protocol stack for synchronisation and error checking. This provides extra security.

IEEE Lays Groundwork for Adoption of DNP3 Protocol as New IEEE Standard
IEEE, the world’s leading professional association for the advancement of technology announced that work is underway for the formal recognition of Distributed Network Protocol (DNP3) as an IEEE standard. Designated as IEEE P1815, the standard will promote interoperability across hundreds of operational systems with thousands of installed devices, as well as strengthening security protocols while maintaining compatibility with existing object models.

Smart Grid starts at TPC 345kV substation in Taiwan

State-run Taiwan Power Co. (TPC) has equipped its 345kV substation HouLi with a real time condition monitoring DTS system providing current ratings and ampacity predictions. A rugged fiber optic sensor cable is attached to all phases of the 4 cable systems, the tie lines as well as the outdoor terminations for real time distributed temperature sensing. Furthermore, the substation’s service tunnels are controlled by DTS in order to activate forced ventilation.

LIOS Technology has provided its integrated Real Time Thermal Rating (RTTR) solution which offers real time ampacity predictions and emergency ratings based on the actual temperature readings and the mathematical model of each configured cable section following the IEC 60287 and IEC 60853 international standards. LIOS’ dynamic cable rating system is a powerful tool for steady state and even transient operations to derive the conductor temperatures of each high voltage power cable phase. Based on the thermal history of the monitored circuits RTTR indicate emergency ratings to ensure save and stable grid operation even during peak hours and dynamic load demands.

By adding continuous and cost – effective monitoring of the electric transmission and distribution grid TPC consequently follows its Smart Grid strategy and helps to utilize electrical energy more efficiently.

Condition Monitoring of high voltage cables: Turning information into extra capacity

Increasing demand for power is forcing power utilities to load power cables to their physical limit, and safety and efficiency concerns are making it more and more critical for operators to understand what is happening thermally both inside the cables themselves, and along the cable route.

Real Time Determination of Thermal Conditions along HV Power Cable Systems
During high-load conditions and under emergency circumstances (such as when a failure occurs in a segment of the grid and power must be shifted to other sections to compensate) it often becomes necessary to load cables right up to the limits permitted by the relevant regulations. In these operational situations, it must be ensured that maximum temperature limits are not exceeded. Due to the increasing complexity of the thermal relationships along cable routes, the ability to continuously measure the temperatures along the cable has proven invaluable, providing critical operational data to engineers, especially in the case of a system faults such as a hot spots that could result in cable failure if they are not corrected.

The intrinsic temperature measuring system DTS based on LIOS Technology’s design, with fibre optic sensors either installed within the power cable’s cross section (FIMT – Fibre in metal tube ) or attached to the exterior of the cable, makes it possible to record the temperature profile along an entire cable route continuously, and to pinpoint the exact location of hot spots within a metre. Since the measuring principle employed is purely optical, the presence of electromagnetic influences, which can result in false sensor signals in other technologies, does not affect the DTS unit.

Distributed temperature sensing is a powerful tool that allows the accurate rating of high voltage power cables in real time, and provides the following operating benefits:

• Reduce power outages or blackouts
• Ensure continuity of supply
• Activate hidden capacity reserves of existing assets
• React quickly to overload conditions
• Conduct precisely and in real-time load predictions as new sources of energy are added to the grid

The temperature profile data, in any desired form or format, can be transmitted via standard interfaces from systems of the OTS product series as required, and be either displayed or further processed by PC, PLC or SCADA systems. As a result of the increasing demands placed on the ability to network and integrate measuring systems into management systems, LIOS offers network components that summarise DTS data from several DTS units and transport or convert it to the required network standards and protocols like Modbus, DNP3, IEC60870-5 or XML based data interfaces.

Dynamic Cable Rating
LIOS also provides an integrated Real Time Thermal Rating (RTTR) package via a well defined interface between its DTS data visualisation software and a commercialised – the industry’s de facto standard – cable ampacity program based on IEC standardised methods (mainly IEC 60287 and IEC 60853). Dynamic rating software couples the accurate temperature data provided by the DTS unit to predictive functions of cable ratings, providing engineers with even more information upon which they can base distribution and load decisions. The result is dramatically more efficient transmission of power, fewer “brown-outs”, and decreased operating costs.
