Abstract

Load flow investigations form an essential prerequisite for power system studies. Existing load-flow techniques, particularly single phase solutions are well developed and streamlined for rapid solutions of very large networks. Conventionally balanced single phase load flow analysis is carried out and balanced model of power system is assumed. Three phase load flow solutions is a useful approach as system unbalance cannot be ignored due to un-transposed transmission lines and unbalance loading in power system. This paper deals with the three phase load flow investigations, which aims to find the optimal operation of National Transmission and Dispatch Company (NTDC), 32-Bus 500/220 kV primary Power System. Sequence components based Algorithm is presented for three-phase networks and is tested for IEEE 6-bus 14-Bus and NTDC 32-Bus practical test system. The performance of the system has been studied for different types of renewable energy resources such as solar and hydel generation units for practical scenarios. Comparison of results validates the potential strength of investigations.

基于序列分量的可再生能源三相潮流算法的实际应用

负荷潮流研究是电力系统研究的重要前提。现有的负载流技术，特别是单相解决方案已经得到了很好的发展和简化，可以快速解决非常大的网络。对单相负荷潮流进行了常规平衡分析，并假设了电力系统的平衡模型。三相潮流解是一种有效的求解方法，因为输电线路未转置和电力系统负载不平衡导致的系统不平衡不可忽视。本文对国家输配电公司32母线500/220千伏一次电力系统的三相潮流进行了研究，目的是找出系统的最优运行方式。提出了一种基于序列分量的三相网络算法，并在IEEE 6总线14总线和NTDC 32总线实际测试系统上进行了测试。针对不同类型的可再生能源，如太阳能和水力发电机组的实际情况，研究了系统的性能。结果的比较验证了调查的潜在强度。
