Research on Design and Security application of AVC System in Plant Station under Interconnected Power Grid

By analysis of voltage regulation of only one voltage system in a nuclear power plant that has two different voltage levels interconnected, research on the sensitivity relationship of related parameters between system voltage regulation strategy and unit and adjacent grid, then propose a design scheme of the AVC control mode of the plant station under the requirements of two different dispatching reactive voltage regulation management, using the parameters of adjacent power grids and units to increase system operation constraints to meet the safety of adjacent power grids and units.
