Callide C Power Station's generator protection system 'ride through capabilities' for various external faults

Abstract

[Abstract]: Callide C Power Station is half owned and operated by CS Energy. It was Australia’s first supercritical coal-fired power station and was commissioned in 2001. CS Energy is a registered participant in the National Electricity Market (NEM) and has a connection agreement with the Australian Energy Market Operator (AEMO) with specified performance standards for Callide C Power Station that it must be capable of delivering at all times. Australia has the largest electrical network in the world by distance and it is the specified performance standards that entire system models and contingencies are based upon. Because of this importance, if there is an incident resulting from a non compliance from CS Energy, they can incur large fines from the Australian Energy Regulator (AER). One major aspect of compliance is the ability for a connected generator to ride through external faults and maintain system voltage and frequency while the fault is cleared. This project aims at building a model to represent a Callide C Generator and Transformer and then simulating large faults of different durations at the connection point. Using the output waveforms from the model, convert the data into the industry standard COMTRADE files so the fault scenarios can be 'played' into the protection relays to determine their stability for each fault type, starting voltage and duration.
