At the beginning of 2018, the production of the 1000th cabinet of the ShEE 22X series was started in the workshops of EKRA Research and Production Enterprise. The “anniversary” was the cabinet of local automatic stability violation prevention (LAPNU) type ШЭЭ 223 0907, it is intended for the 330kV Murmanskaya substation of the branch of PJSC FGC UES - MES of the North-West. As Stepan Reev, Deputy Head of the Department of State Energy Policy of the Ministry of Energy of the Russian Federation, assured energy consumers of the Murmansk Region, the construction of the 330 kV Murmanskaya substation is planned to be completed in March-April 2018. It will become the second largest power supply center in the northern part of the Murmansk region and will create opportunities for technological connection of such large industrial consumers as the Lavna Commercial Sea Port coal transshipment complex and the traction substation of the same name. In addition, it will provide electricity to the construction center for large-tonnage offshore facilities of Kola Shipyard LLC.
Since the facility is connected to the power supply of the Kola Support Zone, a pilot project for the socio-economic development of the Arctic zone of the Russian Federation, the requirements for equipment were the highest. Particular attention was paid to the functions of maintaining the stable and trouble-free operation of the Murmansk transport hub. The LAPNU complex developed at NPP EKRA ensures load stability and synchronous operation of the energy district in the UES of Russia in case of emergency disturbances, provides a standard margin of static stability in post-accident modes, monitors the regime of the control area, fixes emergency disturbances, selects and implements the necessary control actions.
