Branch of OAO «FSK OF ECC» – MES of Volga – began the complex reconstruction of substation 220 kv «Ul’yanovskaya». On a leadthrough technical the rearmament of object of FSK EES will send about 2 milliards of rub During the complex reconstruction of substation 220 kv «Ul’yanovskaya» replacement of all equipment will be carried out, in the number of which two avtotransformatora for 125 MVA, all oily switches will be transferable on modern elegazovye. Planned setting
equipment of relay defence and automation on microprocessor basis. Except for it, on substation CAS of technological process (ASUTP) control, informacionno-izmeritel’naya CAS of commercial, will be inculcated
account of electric power (AIIS KUE), fiber-optic line (FOL) and system of technological supervision is set. All of it will allow to manage the equipment of substation more reliably and operatively. Feature of complex reconstruction of substation
220 kv «Ul’yanovskaya», in that it will pass on an operating object, without limitation users. Substation is in the line of Ul’yanovska, and possibility of its expansion absents. A decision to build on substation new closed distributive is therefore accepted
device (ZRU) 6 kv and to increase the amount of cells from 45 to 86. It will allow to increase reliability of feed of users of city. Basic advantage of the equipment set on substation is his compactness, high reliability and protracted term
exploitations at minimum technical service.
