新型电力系统稳定器的分析

Analysis of the New Power System Stabilizer

随着电网规模扩大，系统中的振荡模式也变得更复杂，由于新型电力系统稳定器PSS4B自身的优势，自然而然的便引起了研究者的足够重视。本文对这种新型的电力系统稳定器的结构优势进行了详细的分析，基于PSASP仿真软件搭建单机无穷大系统，在小扰动和大干扰情况下对传统电力稳定器和新型稳定器进行仿真分析，对PSS4B型电力系统稳定器理论上的优势进行了验证。文章最后对现阶段研究的不足和未来的研究方向进行了总结和展望，指出了未来的研究方向和着手点，为后期深入的研究奠定了基础。

With the expansion of the scale of power grids, modes of oscillation in the system is becoming more complex, because of the advantages of the new power system stabilizer PSS4B, it attracts more and more attention very naturally. In this paper, the structural advantages of this new type of power system stabilizer are analyzed in detail, then based on the software of PSASP to do a simple single machine infinite bus system for example, In the case of small disturbance and large disturbance of the traditional power stabilizer and a new stabilizer for sinmlation analysis. PSS4B theoretical advantage is verified through. Finally the deficiencies of at this stage of the study and future research directions are summarized and prospected
