Generator Testing for Snowy Hydro


PSC’s Genassure generator testing service and PSS/E modelling team have helped Snowy Hydro obtain a detailed understanding of the generator control systems’ capabilities and characteristics, update their models and complete the compliance requirements necessary for the National Electricity Market (NEM).


We worked closely with Snowy Hydro to deliver this detailed programme of work. Each station was assessed separately with test plans, and other documentation prepared for testing the Governor and Automatic Voltage Regulator (AVR) control systems. We worked closely with Snowy Hydro’s engineering team, and test services team to ensure the minimum impact on Snowy Hydro’s operations.

PSC reviewed Generator Performance Standards, the relevant National Energy Regulations (NER) and Snowy Hydro requirements before preparing Test Plans and other documentation for review. Once onsite testing was complete we managed the delivery of compliance, performance and modelling documentation.


Snowy Hydro now benefits from a comprehensive and detailed set of compliance and performance reports.

Snowy Hydro received the necessary generator model updates and validations necessary to comply with the NERs as a member of NEM.
