Abstract

This paper deals with the voltage profile enhancement on the Nigerian 330kV transmission power network using static synchronous compensator (STATCOM). Due to increase in power demand, modern power system networks are being operated under highly stressed conditions. This has resulted to difficulty in meeting reactive power requirement especially under planned or sudden changes in voltages, and hence maintaining the bus voltage within acceptable limits has been a major challenge in the power system network, hence the need for this paper which led to the introduction of Static Synchronous Series Compensator into the Nigeria National Grid (NNG) network for the improvement in electric power transmission . The 330kV 58 bus NNG was modeled in PSAT and implemented in Matlab/Simulink for the compensation of the identified voltage violated buses. Transmission network data obtained from Transmission Company of Nigerian (TCN) Osogbo and was used to model the test network. Result of simulations of the network models reveal that STATCOM reasonably improved the voltage stability of the violated buses in the Nigeria network. The insertion of the STATCOM gave 100% improvement in voltage stability relative to a network without any device.
利用静态同步补偿器(STATCOM)提高尼日利亚输电网效率
本文研究了尼日利亚330kV输电网采用静态同步补偿器(STATCOM)进行电压剖面增强。由于电力需求的增加,现代电力系统网络在高负荷条件下运行。这导致难以满足无功功率需求,特别是在电压计划或突然变化的情况下,因此保持母线电压在可接受的范围内一直是电力系统网络的主要挑战,因此需要本文,这导致了尼日利亚国家电网(NNG)网络引入静态同步串联补偿器以改善电力传输。在PSAT中对330kV 58母线NNG进行了建模,并在Matlab/Simulink中实现了对识别出的电压偏差母线的补偿。输电网数据来自尼日利亚输电公司(TCN) Osogbo,并用于对测试网络进行建模。网络模型的仿真结果表明,STATCOM合理地提高了尼日利亚电网中违规母线的电压稳定性。相对于没有任何设备的网络,STATCOM的插入使电压稳定性提高了100%。
