In this work, the main scheme of electrical connections of a power plant with generators of a given power is designed. The main equipment was selected. The main wiring diagram and a plan of one of the open switchgears have been drawn up. The calculation of normal and emergency operating modes has been made. Short circuit currents are calculated. The choice of relay protection has been made. The calculation of the settings of the relay protection of the generator, block transformer, busbars and power lines has been made.The main primary and secondary electrical equipment was selected in accordance with the current regulatory documents and state standards governing the design, construction and operation of electrical installations and electric power facilities. The proposed design solutions meet the current safety standards in the field of fire protection and labor protection of the operating personnel of the facilities, aswell as the requirements for the reliability and uninterrupted power supply of electricity consumers. The developed scheme of the power plant power output ensures the delivery of the full electric installed power of the power plant to the power receiving network, which is a mandatory requirement when planning the development of the Unified Energy System. |
