摘    要:为了提高含非线性元件电力系统的仿真速度,采用动态相量技术,提出了机电暂态与动态相量(TSP—DP)混合仿真算法,推导了考虑谐波特性的静止无功补偿器(SVC)的动态相量模型,并基于网络分解思想,将外部系统使用传统准稳态模型进行机电暂态仿真;SVC采用动态相量模型进行电磁暂态仿真,并嵌入传统机电暂态仿真程序,2种仿真通过接口母线进行数据交换和仿真协调,以实现全网的TSP—DP混合仿真、在含SVC的1EEE9母线和新英格兰39母线系统上进行了仿真验证,结果说明TSP—DP混合仿真算法具有与DCGEMTP全网电磁暂态仿真相同的精度,比传统混合仿真效率提高了1倍。

关 键 词:网络分解  接口规则  混合仿真  动态相量  静止无功补偿器

Abstract:A hybrid simulation algorithm based on dynamic phasor ( DP ) technology was proposed to accelerate the simulation speed of power system including nonlinear devices.The DP model of static vat compensator (SVC) considering harmonic characteristics was founded. Based on network decomposition method, the external subsystem was represented with conventional quasi-steady state model. SVC was simulated with DP model, and was interfaced into conventional transient stability program (TSP) as electromagnetic subsystem.The information exchange and simulation interaction of two subsystems were implemented by interface bus. Then the TSP-DP hybrid simulation of whole system was accomplished. Case studies were performed on systems of IEEE 9-bus and New-England 39-bus which included a SVC. Simulation results show that the TSP-DP method has the same precision as DCG EMTP simulation and improves the efficiency over twofold than conventional hybrid simulation method.
Keywords:network decomposition  interaction protocol  hybrid simulation  dynamic phasor  static var compensator
