Electrical design of 4×50MW small thermal power plant

Abstract

The paper is the primary and secondary electrical design of a 4×50MW small-scale power plant. We selected the number and type of main transformers of our factory, plan to design two alternatives for main electrical wiring. The equivalent circuit diagram is simplified, and each short-circuit point is calculated in order to provide data protection for the subsequent selection, and then combined with the calculation results of each short-circuit point to select and verify the types of various equipment in the power plant.
