It will be a strong driving force for the development of the national economy that turns the water into electrical energy through hydropower station. So the design work of part of the hydropower plant electrical is very important and only the reasonable solution is necessary to maximize comprehensive benefits for the power station. It is determining that the main electrical wiring USES the expanded unit connection through the analysis of raw data of Da Jin Ping hydropower station and the connecting with the actual situation . Hydro-generator curve of short circuit current calculation is used to calculate short circuit current; Based on electrical equipment manual selecting transformer, bus, circuit breakers, isolating switches and other electrical equipment, and it is necessary to check the selected equipment calibration; and then map out the corresponding electric main wiring diagram and auxiliary power wiring diagram; For...
