IDGC of Centre completed the preparation for winter. One of the features of the preparation this year was the establishment of a more efficient interaction of all energy grid companies. This task is carried out in the new stage of reforming the grid complex of the Russian Federation and consolidation of transmission and distribution grid companies in order to increase security of supply, improve responsiveness to abnormal situations. This formed the basis of orders that were issued by Russian President Vladimir Putin during a working meeting with Chairman of the Management Board of FGC UES Oleg Budargin in August. As part of this power engineers form of a single scheme of operation of networks, unite emergency reserves, establish information exchange, provide interaction between first responding and mobile crews.
In the Yaroslavl region in preparing grid facilities in the region for the autumn-winter period power engineers of IDGC of Centre — Yarenergo division and Yaroslavl EMES of FGC UES demonstrated a high level of interaction. By joint forces the power engineers successfully completed the emergency replacement of ground wire of the overhead 220kV Uglich-Vega, which supplies electricity to the water utility MUP “Water canal” in the city of Uglich. As any interruption in the supply of energy to the water facilities could lead to negative social consequences and harm the environment, the power engineers performed all work without a power outage.
The situation was complicated by the impossibility of organizing a temporary backup power supply for the enterprise, as well as the use of mobile power supplies. At a joint meeting experts of transmission and distribution grids developed a special procedure in which the safe performance of repair work did not affect the water supply of residents of the district centre. For the duration of the work the power engineers of Uglich Distribution Zone of Yarenergo installed cable insertion of cross-linked polyethylene at the intersections of the lines. Thus safe operation and uninterrupted power supply of the social facility was secured. After the repair the cable inserts were removed.
“This case study shows that power engineers work as a team and always are ready to help each other in the area of safety and reliability of electricity supply of customers,” — underlined Deputy Director for Technical Issues — Chief Engineer of IDGC of Centre — Yarenergo division Vladimir Grigoriev.
