摘要
经过3年多的研究开发,电力系统全过程动态仿真软件的主体框架结构的设计、机电暂态过程和中长期过程主要模型的建模、软件主要算法的编程都已完成。3个算例的仿真与分析表明,电力系统全过程动态仿真软件的暂态稳定计算功能仿真结果准确;中长期动态过程仿真结果合理。说明软件所采用的积分方法棗Gear法可以用来仿真电力系统从快速暂态到慢速中长期动态过程的转换,可以自动变阶变步长,算法数值稳定性高,所开发的电力系统全过程动态仿真软件具备了仿真电力系统从机电暂态到中长期动态过程的能力。
After the research and development in past three years, the following items of power system full dynamic simulation software are accomplished. They are the design of its main architecture, the programming of main algorithms for the software, the modeling of the main models for electric-mechanical transient processes and mid- and long-term dynamic processes. The simulation and analysis results of three cases indicate that the transient stability simulation results of power system by using full dynamic simulation software are accurate, the simulation results of mid- and long-term dynamic processes are reasonable. It is also shown that the adopted integration method, i.e., the Gear Method, can be used to simulate the transformation from fast transient process to slow, mid- and long-term dynamic process, the step-size and order can be automatically controlled and the adopted algorithm possesses high numerical stability. Therefore, the phenomena in power system from electric-mechanical transient process to long term dynamic process can be simulated by this software.
