CRITICAL EQUIPMENT SAFEGUARD IN POWER STATIONS USING PLC

Abstract

This novel will speak about the methods to demonstrate all the protections and interlocks available in the
critical equipments of Thermal power station (TPS) and Steam Power Plant (SPP) such as Boiler, Turbine, the
Alternator.These critical equipments are to be protected from abnormal conditions and parameters. The failure of
any one of these equipments will lead to loss of power generation and also cost of these equipments is huge.
Thesafeguard techniques are classified as class a, class b and class c protections. Distributed digital controls and
numerical safety relays play a vital role in providing protections to these critical equipments. Conversely, an
exertion has been made to demonstrate the operational protections with the aid of a programmable logic controller.
