Abstract
One of the sticking points of distributed generation facilities operation is considered—increased shaft vibration activity of the autonomous electric generator unit (AEU), which leads to the shutdown of the gas turbine unit (GTU) by antivibration protection. The main reasons for subsynchronous resonance in the AEU are analyzed. The AEU model based on a GTU, power transformer, and linear and nonlinear loads is presented. The results of simulation modeling of an AEU with a thyristor rectifier as a nonlinear load are obtained, and the influence of rigidity and response time of the power system mechanical component is studied.
带燃气轮机组的自主发电区次同步谐振仿真建模
摘要 分布式发电设施运行中的一个症结--自主发电机组（AEU）轴振动加剧，导致燃气轮机组（GTU）防振保护停机。本文分析了 AEU 亚同步共振的主要原因。介绍了基于 GTU、电力变压器以及线性和非线性负载的 AEU 模型。获得了以晶闸管整流器作为非线性负载的 AEU 的仿真建模结果，并研究了电力系统机械部件的刚度和响应时间的影响。
