Currently,in order to ensure China's energy security,the country is vigorously developing the new energy industry,and hydropower is one of the important components of new energy.Large hydro generator units can provide a large amount of electricity reserves for China,but in practical working situations,hydro generators are prone to various fault problems during operation,requiring careful setting calculations for their relay protection.Starting from this perspective,the article conducts a comprehensive analysis of the electrical characteristics,generator structure,and other aspects of the SX underground power station by reviewing relevant literature in the field and combining it with a practical engineering case.The article also delves into the setting calculation work of the hydroelectric generator relay protection.I hope that the research content can provide theoretical and technical support for the smooth implementation of hydropower in China.
