摘要
文中对智能变电站实时仿真算法进行了研究,分析了智能变电站现场实时仿真测试中测试设备相对较弱的计算能力和复杂仿真的巨大计算量的矛盾。利用智能电子设备(IED)保护动作的延迟特性和实时仿真计算工作量的不平衡性以及X86系统强大的性能,设计了基于变输出时间步长的便携式仿真平台。该仿真平台系统把瞬时突变产生的巨大计算量分散,缓解计算瓶颈,解决了实时计算的超时问题。结合该计算方法,仿真系统采用了模型计算部分和实时通信部分完全独立运行的结构方式,实现了基于X86/X64平台的智能变电站实时仿真测试,并成功运行于实际变电站现场测试。
The real time simulation algorithm of intelligent substation is studied in this paper. We analyze the contradiction between the weak computing capability of field testing device and the huge calculation of simulation. A new portable simulation platform based on variable step-time test calculation is designed through using the protection action of delay characteristics of intelligent electronic device( IED) and the imbalance of simulate calculation and the powerful performance of X86/X64 system. This platform spreads the huge computational of the instantaneous mutation and solves the bottleneck of real-time computing in simulation system. It solves the problem of real-time computation of overtime. Combining the calculation method,the simulation system adopts the structure mode of the model calculation part and the real-time communication part completely independent operation. The real time simulation test of intelligent substation based on X86/X64 platform is realized. The portable simulation platform successfully runs in field test of actual substation.
