摘要:

针对单一仿真软件无法同时考虑复杂电力系统中传统元件、新型元件、复杂控制系统的问题,提出Matlab/SimPowerSystems与电力系统分析综合程序(power system analysis software package, PSASP)联合仿真接口的实现方法。采用多端口等值电路研究软件模型的连接问题,通过PSASP的用户程序接口(user program interface, UPI),调用Matlab引擎API函数实现2个仿真程序的联合仿真;通过控制交互仿真过程,在Matlab/SimPowerSystems中以更精细的步长进行仿真,实现两者以混合步长进行仿真。最后通过搭建光伏并网算例,验证联合仿真接口的可行性与正确性,为电力系统新型元件和控制装置接入大系统后的暂态稳定计算提供了新的方法。

Abstract:

Single simulation software was difficult for complex power system containing traditional elements, new element and complex control system, so the interface technology of co-simulation of Matlab/SimPowerSystems and power system analysis software package (PSASP) was proposed. This paper used multi-port equivalent circuit to study the interface of software models, and called the Matlab engine API function to implement the co-simulation between these two simulation programs, through the user program interface (UPI) of PSASP. Through controlling the co-simulation process, the simulation with finer step was carried out in Matlab/SimPowerSystems to realize the simulation with mixed-step. Finally, PV simulation example was built to prove the feasibility and correctness of the co-simulation method, which could provide a new approach for the transient stability calculation after new components and the control devices of power system connected into large-scale systems.

Key words: power system analysis software package, co-simulation, interface technology, Matlab/SimPowerSystems, mixed-step
