Abstract

This study describes the system simulation and implementation of the system integrity protection schemes (SIPS) in an independent, intensive, and island-type power system. It also elucidates a smart grid plan to provide grid security in this power grid. The proposed SIPS can prevent blackouts that could otherwise result from the transient instability of N-3 contingencies and has been fully implemented and operated. The entire SIPS installation comprises two stages. The first-stage SIPS takes generator tripping system simulation and the second-stage SIPS involves generator tripping, load rejection, and bus-tie switching countermeasures. The proposed SIPS can prevent isolated power system blackout from extreme contingencies system and provide a valuable system simulation experience for similar independent power grids.

Highlights

The electrical power infrastructures of Taiwan are decades old
The first-stage system integrity protection schemes (SIPS) was motivated by the power outage in 1999, which was caused by the crashing of an EHV tower and led to transient instability [16]
The generator tripping scheme will be initiated for any three lines of line A to line F fault or outage; it depends on the STN power flow

Summary

Introduction

The electrical power infrastructures of Taiwan are decades old. The grid is aging and stressed. These goals include four, three, two, and two items, respectively. TPC is implementing the smart grid using a real-time SIPS installation with event based characteristics. SPS are used to involve local operational constraints, but this work proposes the implementation of system-wide SIPS to prevent transient instability of N-3 contingencies in Taiwan power system. The second-stage SIPS is designed to prevent all N-3 contingencies with automation; it performs generator rejection, load shedding, and bus-tie switching. Both of these two stages solve the problem of transient instability caused by N-3 contingencies. SIPS action times must be completed within 250 milliseconds after fault clearance
