Abstract

In modern power systems, the increase of renewable energy generation is a big challenge to the power system stability. The novel stabilizer based on the superconducting magnetic energy storage (SMES) is a promising method for stability enhancement of power system. In the application of SMES, the controller is a key component which determines the capability of SMES. This paper proposes a new controller for SMES to enhance both the damping and the transient stability of power system. The proposed controller utilizes different laws in the different stage of power system transients after a large disturbance. The simulation results show that the system with the proposed controller has smaller states deviation than using the damping controller and less oscillation decay time than using the transient controller when a three-phase-fault happens in the transmission line. Meanwhile, the proposed controller maintains the high damping ratio of the system in steady state.

一种基于暂态分段的中小企业控制方法，以提高电力系统的稳定性

在现代电力系统中，可再生能源发电量的增加对电力系统的稳定性提出了很大的挑战。基于超导磁储能的新型稳压器是一种很有前途的增强电力系统稳定性的方法。在中小企业的应用中，控制器是决定中小企业能力的关键部件。本文提出了一种新型的中小型电网控制器，既能提高系统的阻尼性能，又能提高系统的暂态稳定性。该控制器在大扰动后电力系统暂态的不同阶段采用不同的控制规律。仿真结果表明，当传输线发生三相故障时，采用该控制器的系统状态偏差比采用阻尼控制器的系统小，振荡衰减时间比采用暂态控制器的系统短。同时，该控制器在稳定状态下保持了系统的高阻尼比。
