SUBSYNCHRONOUS RESONANCE MITIGATION USING WIDE AREA MEASUREMENT SYSTEM

Controlling Chaos and Bifurcation of Subsynchronous Resonance in Power System

Abstract. Linear and nonlinear state feedback controllers are proposed to control the bifurcation of a new phenomenon in power system, this phenomenon of electro-mechanical interaction between the series resonant circuits and torsional mechanical frequencies of the turbine generator sections, which known as Subsynchronous Resonance (SSR). The first system of the IEEE second benchmark model is c...

Damping of Subsynchronous Resonance Using a Vsc-hvdc Link

A possible detrimental effect of onshore series compensation in the GB grid is the appearance of subsynchronous resonance (SSR). In this paper, a control scheme for a VSC-HVDC link capable of damping subsynchronous oscillations is proposed in order to effectively counteract the potential damage caused by SSR in steam turbines. The VSC-HVDC link has been modelled to maintain its primary function...

A Unified Framework for Wide Area Measurement System Planning

Wide area measurement system (WAMS) is one of the essential components in the future power system. To make WAMS construction plans, practical models of the power network observability, reliability, and underlying communication infrastructures need to be considered. To address this challenging problem, in this paper we propose a unified framework for WAMS planning to cover most realistic concern...

SIMEFAS: Wide Area Measurement, Protection and Control System in Mexico

This chapter reports on the development of a Wide-Area Measurement System in Mexico entitled SIMEFAS (Sistema de Medición Fasorial). It has been designed to increase the security and integrity of Mexico’s electric power system. Current development of SIMEFAS includes five regional PDCs to which phasor data is sent by PMUs spread over the National Electrical System. Developed applications includ...
