| 摘 要： | 运用状态空间平均法对新型高压直流输电系统进行分析,建立了新型高压直流输电系统的模型。并在开关函数的基础上进行傅立叶变换,通过忽略高次部分,在建模过程中,用开关函数来表示阀的开关状态,其状态组合可以表示整个电压源型换流器的状态,从而可以考虑换流器的自换相过程。结果表明,新型高压直流输电技术具有良好的性能。

| Abstract: | This paper analyses the basic principle of the novel high voltage direct current transmission system,and establishes a mathematical model.The control mode with which the novel HVDC system combines transferring power and compensating harmonic is analyzed through instantaneous reactive power theory when the system is connected to the low voltage grid containing phase-controlled rectifier device that bring a great deal of harmonic.Finally,the feasibility of the method is verified by a prototype. |
