大型工业企业配电网电压无功控制的研究

Voltage and Reactive Power Control for Large Industrial Enterprise Distribution Network

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.

In order to guarantee the power quality of large industrial enterprises and reduce its loss,a strategy of voltage and reactive power control was proposed according to the characteristics of its distribution network.Firstly,control the capacitors based on whether the power factor of monitor point reach the standard,then through the analysis of minimum loss voltage of transformer,to calculate the best voltage of the transformers' low-voltage bus and to control the transformer tap.The simulation results of a l...
