本文提出了一种集中式控制器结构的设计自动再同步的孤岛网络，使用远程同步相量测量单元（PMU）。在多域电力系统模型中测试控制器行为，其中在受控发电机内使用燃气涡轮机的热机械模型来模拟分布式能源（DER），以替代传统的涡轮机-调速器表示。控制器架构使用来自输电和配电级变电站的PMU数据。考虑到电力系统中分布式发电机模型的不同功率调度水平，分析和比较了电域模型和多域模型的整体再同步控制器中的频率控制模块的性能。本文表明，多域模型提供了更详细的表示涡轮机的行为和更好的调整控制信号的行为在重新同步过程中。
This paper presents the design of a centralized controller architecture for automatic re-synchronization of islanded networks that uses remote synchrophasor measurements from Phasor Measurement Units (PMUs). The controller behaviour is tested in a multi-domain power system model, where a thermo-mechanical model of a gas turbine is used within the controlled generator to model a Distributed Energy Resource (DER), in substitution of a traditional turbine-governor representation. The controller architecture uses PMU data from substations at transmission and distribution level. Considering different power dispatch levels of the distribution generator model in the power system, the performance of frequency control module inside the overall re-synchronization controller has been analyzed and compared for both electrical-domain and multi-domain models. This paper shows that multi-domain models provide more detailed representation of the turbine behaviour and a better adjustment of the control signal behavior during the re-synchronization process.
