The branch of the System Operator Kola RDU together with the branch of PJSC ROSSETI – Karelian SPES successfully conducted comprehensive tests and put into operation an automated remote control system for the equipment of the 330 kV Murmansk substation (PS) from the dispatch center. This is the first such digital project in the power grid of the Murmansk Region at the power grid facility of PJSC ROSSETI.
The dispatching center of the System Operator has started remote control of the equipment of the 330 and 150 kV open switchgear (OPU) of the 330 kV Murmansk PS. Remote control is carried out using automated switching programs (APP). This is a sequence of actions presented in the form of a computer algorithm when switching. It ensures the execution of switches by sending commands directly to the automated process control system (automated process control system) of the energy facility, and also monitors the correctness of the execution of commands in automatic mode.
The introduction of remote control increases the reliability of operation and the quality of control of the electric power regime of the Murmansk region power system by reducing the production time of operational switches, reducing the risk of erroneous actions of personnel, increasing the speed of implementation of control actions to change the topology of the electrical network, reducing the time for the elimination of technological violations.
"The use of the digital system will allow the use of automated switching programs during the commissioning or commissioning of power transmission lines connected to the feeding center, including the 150 kV Kola – Murmansk VPP, through which the power output of the newly built Kola VPP is carried out," says Andrey Schennikov, director of the Kola RDU.
During the implementation of the project, specialists of the technological functional unit and the information technology unit of the Kola RDU, together with specialists of the Karelian SPES, did a lot of work on setting up the substation's automated control system, the operational information complex in the Kola RDU, developed standard switching programs for overhead lines and equipment and prepared automated switching programs based on them. Within the framework of the project, the necessary regulatory and technical documentation was revised and put into effect, additional training of dispatching and operational personnel was conducted, additional measures to ensure information security were implemented.
The start of operation of the digital system was preceded by comprehensive tests. Kola RDU created circuit-mode conditions for testing an automated remote control system.
Before putting the system into operation, the readiness of the personnel of the dispatch center, the 330 kV Murmansk PS, to perform remote control functions was checked. On the basis of the training center for the personnel of the Kola RDU, a control system-wide emergency training was successfully conducted to eliminate violations of the normal regime in the Murmansk Region power system using remote control. The results of complex tests and successfully conducted joint emergency training confirmed the readiness of the Kola RDU to perform the functions of remote control of the equipment of the 330 kV Murmansk substation.
The 330 kV Murmansk substation became the first substation in the operational zone of the Kola RDU, which implemented remote control from the dispatch center. According to its characteristics, the 330 kV Murmansk substation fully meets the requirements for new generation substations. In particular, modern equipment and automation tools have been installed at the power facility, providing remote control from the dispatcher center of the System Operator.
Currently, after performing the necessary checks, the Kola RD has started remote control of the 150 kV equipment, as well as the operating modes (active and reactive power) of the Kola WPP.
