Title Design of the electrical power grid area and power plant
Abstract
This paper is the design of the regional power grid and power plants. The
main content is based on the original data to determine the connection
scheme of the regional power grid by economy and technology, selection of
thermal power plants and hydropower generators and transformers of models,
and identify the main electrical wiring in thermal power plant, and then
choose and check calculation of short circuit current and the main electric
equipment such as circuit breaker, isolating switch, current transformer,
relay finally, the generator transformer protection configuration and
line.The paper includes a total investment of two programmes, two
generators and transformer power plant capacity calculation and model
selection, short-circuit current calculation, the main equipment
isolation switch check and selection, the configuration of relay
protection.
Keywords regional power grid the main electrical wiring equipment calibration short circuit current
