【摘要】 随着电力市场化和电力负荷的不断增长,以及对电力系统的安全性更加重视,以大功率电力电子器件为基础的灵活交流输电技术(FACTS)已经成为人们研究的热点。FACTS装置可以灵活快速的控制系统,可以有效地提高输电容量,增强系统稳定,提高系统的可靠性和安全性,因此对FACTS设备的建模与相关仿真研究一直是电力系统数字仿真所关注的问题之一。本论文致力于FACTS设备的建模和仿真研究,主要内容可以概括为以下几个方面：1.对静止无功补偿器(SVC)实际设备进行调研工作,详细阐述了SVC的工作原理和数学模型,并在此基础上为电磁暂态仿真程序ETSDAC添加了SVC模型,同时结合具体算例,与通用电磁暂态计算程序EMTP作对比,验证了该模型的正确性。2.利用该模型,在ETSDAC中搭建单机系统算例,结合机电暂态计算程序PSASP,分别进行电磁暂态-机电暂态混合仿真和纯电磁暂态计算、纯机电暂态计算的结果对比；利用华中六省市联网系统实际算例,设置不同的故障类型,分网进行混合仿真计算,将仿真结果与纯机电仿真结果对比分析,证明了本论文工作的实用性和合理性。3.为电力系统全数字仿真装置ADPSS开发与可控串联电容补偿(TCSC)控制装置的接口程序,使ETSDAC能带上TCSC实际控制设备进行电磁暂态计算,并利用含TCSC的实际系统来进行仿真计算,体现了本论文工作的实用性和必要性。更多还原

【Abstract】 With deregulation of electric industry and continuous increase of electric load, more attention is paid to the security of power system. The Flexible AC Transmission System (FACTS) based on high power electronic elements is becoming the research focus, since it has a lot of advanced characteristics, such as, flexible and rapid control of power system, improvement of transfer capability of transmission network, to strengthen the stability, reliability and security of power system, to make power system highly controllable and so on. So the modeling and related simulation analysis of FACTS have been the concern of power system digital simulation.The objective of this dissertation is the FACTS modeling and simulation research. The contents in the paper include the following aspects:1. With the investigation of the actual equipment of Static Var Compensator (SVC), the physical structure and mathematical model of SVC are illustrated in detail. And based on that, the SVC model is added in ETSDAC, a commercial electromagnetic transient simulation program of CEPRI. Comparing the results in a testing case with ETSDAC and EMTP, the methodology of SVC model is validated.2. A single-machine system is built with SVC model. Using ETSDAC and PSASP (a commercial electromechanical transient simulation program), the electromagnetic transient and electromechanical transient hybrid simulation is performed on the study system and the results of those simulations are compared. Furthermore, studies are made on different problems in Central China power grid with the similar methods. And the practicality and rationality of the thesis work are validated.3. The interface between the Advanced Digital Power System Simulator (ADPSS) and Thyristor Controlled Series Capacitor (TCSC) is developed. With its application, the electromagnetic transient simulation with actual TCSC control equipment can be realized. And the thesis work’s practicality and necessity are validated.更多还原
