研究多变量系统等效开环过程(effective open-loop process，EOP)理论在电力系统多柔性交流输电装置(flexible AC transmission system，FACTS)协调控制量化分析中的应用，并提出基于EOP的多FCATS阻尼控制器交互作用分析方法及量化指标。推导电力系统阻尼控制框架下的 EOP，在此基础上建立用于多FACTS阻尼控制器分析的阻尼控制等效开环过程(damping control effective open-loop process，DCEOP)。提出基于 DCEOP 谱半径和多变量 Nyquist 推广定理的多FACTS阻尼控制器交互影响分析方法，可以判断系统中是否存在多FACTS阻尼控制器的负交互作用。进一步推导并提出基于DCEOP的多FACTS交互风险因子和交互作用因子，实现了多FACTS阻尼控制器协调控制及交互作用的量化分析。最后，通过算例分析验证了所提方法的正确性以及在实际电网中应用的可行性。

This paper studied the interaction among multiple FACTS damping controllers in power system, and presented a novel multi-FACTS interaction analysis method on the base of effective open-loop process Theorem. First of all, the EOP under the framework of power system damping control was deduced, and the DCEOP for multiple FACTS interaction analysis was established. Then a new interaction analysis method based on DCEOP spectral radius and multivariable promotion Nyquist theorem was proposed, which can determine whether the system contains negative interactions among FACTS damping controllers. Furthermore, two novel interaction quantitative indexes based on DCEOP were derived and proposed, which offer quantitative interaction analysis for multiple FACTS controllers. Finally, the simulation results for typical system as well as a practical power grid verify the validity and efficiency of the method proposed in this paper.
