计及STATCOM的受端换流站容性无功配置策略研究

Study on Capacitive Reactive Power Allocation of Receiving Converter Station Considering STATCOM

加装STATCOM装置是解决联于弱交流系统的高压换流站电压波动问题的重要手段之一。为了提高考虑加装STATCOM后受端换流站容性无功配置研究计算的效率,在分析交直流系统的稳态运行原理和STACOM的暂稳态无功特性的基础上,建立了计及STATCOM的受端换流站容性无功单组容量优化模型和无功配置方法。以我国南方地区某背靠背联网工程为算例,验证了该模型和方法的合理性,可适用于受端换流站工程前期阶段的容性无功配置方案研究。

Adding STATCOM device is one of the important means to solve the problem of voltage fluctua⁃tion in converter station connected to weak AC system.In order to improve the efficiency on the capacitive reactive power allocation study and calculation of the receiving converter station after adding STATCOM,the optimization model of sing group capacity and the reactive power allocation method for the receiving converter station considering STATCOM is set up and designed on the basis of analyzing the transient oper⁃ation principle of AC and DC system and the transient operation feature of STACOM.One certain back⁃to⁃back networking project in the south of China is taken as an example to verify the rationality of the model and method,which can be used for the study of capacitive reactive power allocation scheme in the early stage of the receiving converter station project.
