摘要

对传统紧急功率支援模块进行了改进，提出了幅值自适应的阶梯式紧急功率支援控制技术。将功率提升方式由斜坡上升改为阶梯式，引入了能够实时反映系统稳定性的信号，并根据反馈信号来确定紧急功率支援的幅值。文中阐述了该新型紧急功率支援模块的基本原理，介绍了参数整定的方法以及反馈信号的选取，并通过PSCAD仿真验证了该控制模块的可行性。仿真结果显示，该模块实现了根据反馈信号自适应确定功率提升幅值，在充分发挥直流系统输电能力的同时兼顾了换流器交流母线的电压稳定性，解决了传统紧急功率支援模块参数整定困难、适用性差的缺点。

Abstract

By improving the traditional emergency power support module，a new type of emergency power support technology is proposed.The power is stepped up to the value set instead of ramping up，and signals capable of reflecting the stability of the system in real time are introduced to determine the amplitude value of the emergency power support.A description is made of the basic principle of the new emergency power support module，the method of parameter setting，and the selection of the feedback signals.A simulation model is developed in PSCAD/EMTDC to verify the feasibility of the control module.Simulation results show that the controller presented can automatically determine the increment step of the active power according to the feedback signals.The new method can make full use of the transmission capacity of the DC system while taking into account the voltage stability of AC system.Furthermore，the proposed emergency power supporter can solve the problems in parameter setting and improve the applicability of the emergency power support module.
