At the end of the last week, Kyiv hosted a working meeting between the representatives of SE NPC Ukrenergo and Belorussian transmission system operator RUP ODU. The parties discussed a number of important issues regarding the parallel operation of the power systems of the two countries.
In particular, they discussed the issue of defining a dispatching centre responsible for the elimination of overload on the power transmission line at the crossing of Ukraine and Belarus.
“Based on the conducted research, we considered the possible ways of resolving this issue and reached an agreement regarding our further steps,” said Vitalii Zaichenko, Deputy CEO for Operational Management – Chief Dispatcher. “The joint position of Ukraine and Belarus on regulating the flows between Ukraine and Belarus will be considered in November during the regular meeting of BRELL participants*. This is an urgent issue today, which can affect the stability of both power systems and requires resolution since our power systems are synchronised. After integration into ENTSO-E, this problem will cease to exist,” noted Vitalii Zaichenko.
At the same time, during the meeting, the parties considered and approved draft documents regarding data exchange between neighbouring power systems and signed the “List of metering points and composition of telemetering and remote alarm system, transmitted from RUP ODU to SE NPC Ukrenergo/from SE NPC Ukrenergo to RUP ODU, which allows performing operative calculations of operation modes of the power systems of Ukraine and Belarus.
The parties also agreed on the exchange of experience in operating the devices of the transition regimes** monitoring systems and operating the automatic load-frequency control system within the IPS of Ukraine.
* Power circle of Belarus, Russia, Estonia, Latvia and Lithuania (BRELL) – synchronous regime of power systems operation based on the agreement dated 7.02.2001. Provides for the connection of power transmission lines of five countries into a single power circle with the general principles of organisation of joint operation, electricity exchange and mutual support in the case of emergency.
** Transition regime means a shift in the power system parameters from one stable condition into another because of, for example, switching off or switching on of generators, lines, load, short circuit, etc. TRMS allows collecting synchronous data on electric parameters of the power system in case of emergency. This will allow a user to detect the reason of interruptions in the grid as well as forecast the occurrence of emergencies.
