南方电网无功电压问题分析

摘要

阐述了无功电压控制策略,介绍了南方电网无功配置情况、无功平衡情况及N-1电压水平情况,分析了南方电网无功电压运行存在的问题,并从电网运行方式安排、静态无功补偿、无功分层分区平衡控制、动态无功支撑、电压无功自动控制和电压无功监督管理等方面对南方电网的无功电压工作提出建议.%The paper expounded the reactive voltage control strategy and introduced the conditions of reactive conifguration, reactive balance and N-1 voltage level in southern power grid. Analysis was made to the problems existing in reactive voltage operation of southern power grid. This paper gave some advices of reactive voltage working from the aspects of power grid operation arrangement, static reactive power com-pensation, reactive layered and zoned balance control, dynamic reactive power support, automatic voltage control (AVC), and voltage reactive power supervision and management.
