Hotline of power engineering specialists:
On the winter full operation day, the volume of consumed power in grids of IDGC of Centre - Belgorodenergo division amounted to 1,172 MW. Hourly test measurements of instantaneous values of active and reactive power for the 14th time were carried out without the participation of personnel, by means of an automated electricity metering system implemented at all 181 substations of 35-110 kV.
Last year, the demand for electricity from consumers connected to the branch’s grids grew by 6%, from 1,109 in 2017 to 1,172 MW in 2018.
Control hourly measurements of the instantaneous values of active and reactive power, voltage, current and other parameters of electrical installations were carried out on the winter day of 19 December 2018, in order to check the load on the electric grid facilities, the availability of power reserves to provide electricity to existing consumers and to connect new ones.
The obtained data will allow to optimize the operation mode of power equipment, monitor the status of power centres, to which it is difficult to connect new customers, to develop measures to reduce electricity losses in the grids. In addition, the indicators of the full operation day are the basis for development of schedules for temporary blackouts, the use of which makes it possible to prevent the development of emergency situations as soon as possible.
According to the leading engineer of the electric modes service of Belgorodenergo, Ilya Balashov, about 360 people used to perform this task, who were continuously at the substations for 24 hours and took measurements, and the data processing took about a month. After implementing the automated electricity metering system at power centres and upgrading communication channels, the power engineers were able to remotely take the basic electrical parameters of electrical installations in real time. This not only reduced costs, but also simplified the analysis of information, reduced the influence of the “human factor” and the likelihood of measurement errors.
