摘要
直流输电系统HVDC(H igh Voltage D irect-Current Power Transm ission)的控制问题对电力系统的安全稳定运行具有深远的影响,但其系统本身所具有的强非线性特性,需要先进的控制技术以提高系统的性能。在总结传统控制策略的基础上,综述了现代控制技术在高压直流输电系统中的应用研究现状,分析了各种控制算法在直流输电系统中应用优势和缺陷。针对多馈入直流输电系统出现后面临的更为复杂的问题,如直流系统间的电磁耦合关系、系统内部的协调优化问题等,给出今后发展的趋势和需要关注的问题。
The controls of HVDC have an important influence on the security and stability of the power systems. As a strictly nonlinear system, HVDC needs modern control theories to improve the performance of the system. Based on analysis of traditional control strategies, this paper reviews the recent researches of the application of the modern control technologies into the HVDC systems. Every control strategy has its own advantages and defects. The absence of rnulti-infeed HVDC systems results in many complex problems, such as the electromagnetic coupling between HVDCs and the coordination of the components in the systems. The directions of development and matters with attention are put forward in the final part of the paper.
