Renovation and Optimization Measures in the Replacement of the Generator-Transformer Unit Protection Device in a Large-scale Hydropower Station
In the replacement of the generator-transformer unit protection device in a large-scale hydropower station,the current and voltage sampling circuit and the program configuration are renovated based on the analysis of some important renovation points of the protection system.Protection configurations are added,which make the protection system more in line with relevant national regulations,and effectively improve the rationality and reliability.Also,devices from different manufactures are adopted to avoid the safety risks caused by software and hardware defects in the equipment family.It can be useful reference for the optimization design and renovation of similar generator-transformer unit protection systems in hydropower stations.
