Operation and management of such substations is based on the software and hardware complex of a digital substation, divided into structural levels (process, connections and substations), which are interconnected by Ethernet local area network segments.
OOO ServisMontazhIntegratsiya offers modern solutions in the field of creating control systems for power facilities using the latest IEC61850 protocol. IEC 61850 standardized communication processes and the design process itself on a global scale. This means that users are no longer dependent on one manufacturer, and the number of interfaces which are incompatible with each other has been significantly reduced. IEC 61850 protocol permits:
- Reduce the time and cost of introducing MV and LV smart devices into distribution grid management systems due to the simulation approach implemented in the standard.
- Increase visibility and manageability of medium and low voltage sections of the network, including areas of distributed generation.
- Improve the quality of services through partial or complete decentralization of feeder automation systems.
- Add support for many additional features (low voltage feeder load balancing, voltage variation limits control, etc.).
- Optimize equipment and reduce site visits.
Automated power control systems perform the following functions:
- monitoring of operation and management of power equipment;
- prevention of emergencies;
- increasing the level of information support for process and operational personnel;
- increasing reliability of control system through the use of modern technical devices based on electronic and computing tools and the availability of self-diagnostics;
- technical measurement of energy consumption;
- providing operational personnel with relevant operational and historical process information, reports, including those on paper.
Automated power control systems have following features:
- Monitoring of signal reliability and faultless operation of communication lines.
- Continuous collection of electrical equipment parameters in accordance with the approved list of parameters. Data collection is carried out via standard exchange protocols (Modbus, Profibus, IEC61850, IEC60870, etc.).
- Each signal has a timestamp and signal quality flag in accordance with IEC61850 standard.
- Storage of archives of events and trends of analogue parameters on dedicated archive servers.
- Full redundancy of all system components: controllers, servers, power supplies, switches, communication lines.
- Reliable multi-layer structure of communication lines via network redundancy protocols such as RSTP, PRP, MRP.
- System components comply with IEC 61850-3: increased requirements for climatic design, vibration resistance, shock resistance, EMC.
