摘要
低频振荡是大型交直流并联系统安全稳定运行的潜在威胁。快速有效的直流调制方法是解决低频振荡的有效手段。介绍了在上海交通大学开发的大规模互联系统小信号稳定分析软件包中实现的自定义直流调制功能。自定义直流调制是利用元件连接的思路建模,按照软件中统一元件连接建模的方法参与形成系统状态方程。该功能为直流调制方法的进一步研究奠定了基础。算例验证了自定义直流调制的正确性。
Low frequency oscillation is the potential threaten to the stability and security of the large AC/DC interconnected power system. Fast and effective modulation controller is one of the effective ways to solve the problem. Introduction about the realization of user defined modulation controller （UDMC） in small signal analysis package （SSAP） developed by Shanghai Jiaotong University, which has been applied in analysis of the large power system, is present in this paper. The modeling of UDMC is based on the component connection modeling idea, and UDMC accords with the universal component connection method in SSAP to participate in the formation of system state matrix. UDMC is the foundation for future research on modulation controller. Analysis of specific case validates the correctness of the UDMC function.
