摘要
在地区电网系统中由于电容器投切不及时,损坏率高,维修时间长,对用户和发电厂的电容投入运行管理不到位等一系列问题,导致电网对无功调节和控制不利,有时还出现电网向大用户倒送无功的现象,电网的电压质量低下,电压稳定性差,无法达到电网考核标准。本文通过对准格尔旗电网无功电压存在问题进行分析,提出了加强对地区电网无功补偿装置以及电厂和用户无功考核管理等方面来提高电网电压质量,以保证电网安全、稳定、经济的运行。
In the district power grid system, due to the capacitor do not fast to cast, damaged rate is high, maintenance time is long, to the user and power plant capacity in the operation management is not in place etc. lead to the power grid of reactive power regulation and control harmful, sometimes appear the power grid to the big user deliver the reactive phenomenon, the power grid voltage quality is low, voltage stability is poor, beyond the reach of the network evaluation standard. the paper through to the district power grid reactive voltage problems analyzed, put forward to strengthen the reactive power compensation device、the user reactive assessment management to improve the quality of power grid voltage, to ensure the safety of power grid, stable and economic operation.
