摘要

提出了一种新的初始化技术，用于电力系统暂态分析中控制图的仿真。新技术已经在EMTP(电磁瞬变程序)中实现和测试。它基于可在其他瞬态分析应用程序中重用的通用思想。第一个目标是通过避免不必要的模拟启动瞬态来显著减少计算时间。第二个目标是根据期望的稳态条件，提高控制块变量初始化的自动化水平。新方法已用于魁北克水电网络的研究，该网络有40多台受控机器，总发电量为30吉瓦。将时域仿真得到的快速稳态解与期望的稳态工况进行比较，验证了该方法的有效性。

New initialization method for controls in transient analysis

This paper presents a new initialization technique for the simulation of control diagrams in transient analysis of power systems. The new technique has been implemented and tested in the EMTP (Electromagnetic Transients Program). It is based on a generic idea reusable in other transient analysis applications. The first objective is to significantly reduce computation time by avoiding unwanted simulation startup transients. The second objective is to increase the level of automation for the initialization of control block variables based on desired steady-state conditions. The new method has been used for a study in the Hydro-Quebec network with more than 40 controlled machines aggregating the generation of 30 GW. Comparing the fast steady-state solution obtained through time-domain simulation, with the desired steady-state operating conditions, provides validation.
