摘要/Abstract

摘要： 混合动态仿真是实现电力系统动态仿真验证的重要方法。提出的混合动态仿真方法将包含恒定功率与冲击功率的实测数据直接注入仿真子系统，实现子系统间解耦。该方法避免了对外部系统动态等值可能引入的仿真误差，依托商用软件PSASP提供的负荷模型及固有的冲击扰动模块，简单易实现，避免了采用用户程序接口/自定义接口（UPI/UD）语言编写接口程序，实用性较强。以IEEE 10机39节点测试系统和某省级电网算例，验证了该方法的有效性。

Abstract: Hybrid dynamic simulation is an important tool for power system simulation and validation. In this paper, a hybrid dynamic simulation method of power system is proposed based on impulse load injection, which directly injects the measured data containing constant power and impulse power into the simulation subsystem to achieve decoupling between subsystems. This method avoids the simulation error that may be caused by the dynamic equivalent of the external system. Based on the load model provided by the commercial software PSASP and the inherent impulse disturbance module, the proposed method is simple and easy to implement, and avoids the use of UPI/UD to write the interface program, thus having high practicality. A case study is conducted on an IEEE 10 machine 39-bus test system and a provincial power grid, which has verified the effectiveness of this method.

Key words: hybrid dynamic simulation, impulse load, constant load, measurement information, error tracing
