| 摘 要： | 为使离线电磁仿真软件实时数字仿真仪(real timedigital simulator,RTDS)能够接收能量管理系统(energymanagement system,EMS)的在线潮流数据,将系统运行的实时数据传送给RTDS,实现RTDS的在线化仿真,自动跟踪电网的即时状态。研究并设计了基于南方电网RTDS仿真模型的EMS潮流数据在线系统,通过将来自EMS的潮流数据在RTDS仿真系统模型上进行可观测性分析、状态估计计算、不良数据的检测与辨识等在线化处理,并采用RTDS-GTNET卡的DNP3.0通信协议将估计结果作为仿真初始数据送入RTDS进行仿真,使RTDS仿真基态数据更加接近于系统的实际运行状态,实现了RTDS的在线化仿真。以云南电网仿真系统为例进行了测试,结果表明所开发系统具有较高的准确性。

| Abstract: | To make the off-line electromagnetic simulation software,namely the real time digital simulator(RTDS),enable to receive online power flow data of energy management system(EMS) and to send the real-time operation data of power system to RTDS to implement online simulation by RTDS and automatically tracking immediate state of power system,based on the RTDS model of South China power grid an online simulation system of EMS power flow data is developed.By means of performing online processing such as observability analysis,calculation of state estimation and detection and recognition of bad data and by use of DNP3.0 protocol of RTDS GNTET card,the estimation results,which is regarded as initial data for the simulation,are sent into RTDS to carry out the simulation,thus the ground state data of RTDS simulation is closer to actual operation state of power grid and the online simulation by RTDS is realized.The developed online simulation system is tested and verified by RTDS simulation model of Yunnan power grid,and the results show that the developed online simulation system is accurate. |
