摘要:

为了保证大型工业企业的用电质量,减少电网损耗,根据其电网特征提出了相应的电压无功控制策略;首先以监测点功率因数是否达标为依据调控电容器的投切,然后通过对变压器最小损耗电压的分析,推出变压器低压母线的最佳运行电压及变压器分接头的调控方式,针对某大型钢厂配电网实测数据所做的电压无功控制仿真分析结果,证明了该控制策略的合理性和实用性.

Abstract:

In order to ensure the power quality of large industrial enterprises and reduce the loss of power grid, the corresponding voltage reactive power control strategy is proposed according to the characteristics of its power grid. Firstly, the switching of capacitors is regulated according to whether the power factor of the monitoring point meets the standard, and then through the analysis of the minimum loss voltage of the transformer, the optimal operating voltage of the transformer low-voltage bus and the regulation method of the transformer tap are introduced, and the simulation and analysis results of voltage reactive power control made on the measured data of the distribution network of a large steel mill prove the rationality and practicality of the control strategy.
