Engineers of IDGC of Centre – Belgorodenergo division Alexander Tashkin and Sergey Sayenko became the authors of innovations aimed at increasing the efficiency of power transmission and reduction of losses. Their developments were awarded special certificates and included in the register of rationalization proposals of IDGC of Centre.
The deputy chief of Valuisky Distribution Zone for sale of services Sergey Sayenko developed a number of organizational and technical measures aimed at identifying facts of theft of electricity in the power grid.
In the first phase of activities a kind of database is formed, or a "black" list of customers who stole electricity, and consumer meters, distorting the amount of electricity used. The second step to bring the customers to normal usage Sergey Sayenko proposed new calculation tools and methods for identifying such meters. After the introduction of these measures net supply of electricity with legal entities in Valuisky district, who stopped using the "modified" meters, increased by 1.64 million kWh in comparison with 2015. Power losses in the distribution network were reduced at the same magnitude. The total positive effect of the set of organizational and technical actions carried out in 2016 amounted to at least 3.28 million kWh.
A leading engineer of the office for energy saving and energy efficiency Alexander Tashkin in his rationalization proposal suggested supplementing the design of package transformer substations of 6-10/0.4 kV with special capacitors for compensation of reactive power losses in power transformers. This will reduce the reactive power flows and, as a consequence, technical losses in the distribution network of 6-10 kV. Payback period with little additional cost (about 2%) does not exceed 2 years. The author notes that if at the planned replacement and installation of new transformers in advance to take care of their compensation of utility reactive power losses, this will reduce load losses in the 6-10 kV network. After all, the effect of reactive power compensation only in one transformer is from 3.6 to 9 thous. kWh per year, depending on the rated power. Taking into account that IDGC of Centre has on the balance more than 110 thousand transformers of 6-10/0.4 kV, the cumulative effect can be very significant.
The certificates for innovations were registered in accordance with the provision on rationalization activities of IDGC of Centre, aimed at searching for new technical solutions designed to improve the quality and reliability of electricity supply to customers.
