In this research work investigation of reactive power necessity at standard voltage level is practiced. The 39-bus test network modeled in mipower application is a part of Rajasthan power system, attached with North Regional National Grid synchronized at 765 kV voltage level. State power utilities are unable to obtain the profoundness in providing, static or dynamic compensation at multiple voltage available within the grid. Reactive power drawl from the network end is judged and analysed by placing imaginary generator at available voltage level. In Rajasthan power system voltage level arrays from 765 kV to 33 kV and the utilities are puzzled in managing var penetration due to poor estimation. As a result, higher loading levels and abrupt line tripping raises losses and reduces system reliability. The simulation case studies presented herby from the database of financial year 2018-19 will be envisaged by the utilities after evaluation is over. Presently State Load Dispatch Centers deliver instruction to substations to utilize any compensation device available without prior calculation. But this paper underlines a way to access the effects on voltage profile, losses etc. in power system structure after planned var support at optimum voltage level. Case studies over real time network is detailed, to check the observability for a load of 370 MW. The impact of practices followed is observed for the designed network.

通过实时网络的无功功率分配评估电压变化性

在这项研究工作中,对标准电压水平下无功功率的必要性进行了研究。在mipower应用中建模的39总线测试网络是拉贾斯坦电力系统的一部分,该电力系统与北部区域国家电网相连,在765 kV电压水平下同步。州电力公司无法获得在电网内可用的多种电压下提供静态或动态补偿的深度。通过将虚构的发电机置于可用电压水平来判断和分析来自网络端的无功功率消耗。在拉贾斯坦邦电力系统中,从765 kV到33 kV的电压水平阵列,由于估算不佳,使公用事业公司难以管理var的渗透。结果,较高的负载水平和突然的线路跳闸会增加损耗并降低系统可靠性。评估结束后,公用事业将设想从2018-19财政年度数据库中提出的模拟案例研究。目前,国家负荷调度中心向变电站提供指令,以利用任何可用的补偿装置,而无需事先计算。但是,本文强调了一种在计划的无功支持最佳电压水平后访问对电力系统结构中的电压分布,损耗等影响的方法。详细介绍了实时网络上的案例研究,以检查370 MW负载的可观察性。对于设计的网络,观察到了实践的影响。目前,国家负荷调度中心向变电站提供指令,以利用任何可用的补偿装置,而无需事先计算。但是,本文强调了一种在计划的无功支撑处于最佳电压水平后访问对电力系统结构中的电压分布,损耗等影响的方法。详细介绍了实时网络上的案例研究,以检查370 MW负载的可观察性。对于设计的网络,观察到了实践的影响。目前,国家负荷调度中心向变电站提供指令,以利用任何可用的补偿装置,而无需事先计算。但是,本文强调了一种在计划的无功支持最佳电压水平后访问对电力系统结构中的电压分布,损耗等影响的方法。详细介绍了实时网络上的案例研究,以检查370 MW负载的可观察性。对于设计的网络,观察到了实践的影响。
