基于PSS SINCAL的农村电网优化分析

An Analysis of the Optimization of the Rural Power Grid Based on PSS SINCAL

随着电气化程度的提高和电力电子设备等非线性负荷的大量使用,农村电网的三相不平衡和无功问题越来越突出。针对这些的问题,应用PSS SINCAL(Power System Simulation SIEMENS Network Calculation)软件进行优化分析。对于三相不平衡问题,优化后系统的平衡度有明显的提高;对于无功不足问题,优化后可计算出补偿装置的位置和容量,从而改善功率因素,减少了线路损耗。

With the improvement of electrification degree and extensive use of power electronic devices and other nonlinear loads,the three-phase unbalance and reactive power problem of rural power grid are more and more prominent.This paper,targeted at these problems,applies PSS SINCAL software for optimization analysis.For three-phase unbalance,the balance degree of system after optimization has obvious enhancement.For the shortage problem of reactive power,after optimization the software can calculate the location and capacity of reactive power compensation device,thereby it can improve the power factor and reduce line losses.
