摘要
为解决呼盟系统火电机组存在的次同步振荡问题,提出一种基于静止无功补偿器的次同步振荡阻尼控制。采用RTDS实时仿真工具与实际系统控制器搭建全闭环实时数字物理仿真平台,实现验证控制策略、优化控制参数及检验控制器有效性等工作。通过频率扫描法仿真实验寻找次同步振荡中心频率,大扰动仿真实验表明,静止无功补偿器能有效抑制火电机组轴系次同步振荡,验证了控制策略正确性及可行性,为现场调试提供指导。
To solve the problem of sub-synchronous oscillation of thermal power plants in Hulunbeier, this paper introduces a novel strategy based on Static Synchronous Com-pensator. A closed-loop test system is established based on the real time digital simulator( RTDS) and the real controller. The simulation result has verified that the proposed control scheme can significantly reduce the oscillation and keep the power plant stable. This simulation platform provides technical gui-dance for the field test.
