某地区电网全电磁暂态仿真分析及次同步谐振风险分析

针对和田地区电网新投运三台SVG后,可能存在的次同步谐振风险开展了研究。主要内容包括:线路及机组参数校核、光伏站及光伏站SVG建模、新投运SVG模型与特性研究、和田地区全电磁建模和振荡风险仿真与分析。本研究采用时域仿真法研究和田地区电网次同步振荡风险。

In this paper, the possible risk of subsynchronous resonance after the new operation of three SVGs in Hetian Power Grid is studied. The main contents include: line and unit parameter check, photovoltaic station and photovoltaic station SVG modeling, new operation SVG model and characteristic research, full electromagnetic modeling and oscillation risk simulation and analysis in Hetian area. In this study, the Time Domain Simulation Method is used to study the risk of subsynchronous oscillation in Hetian Power Grid.
