Abstract
With the rapid development of China's power industry, the major power system capacity and expanding the regional power grid. Protection devices are widely used in power systems, Rural and small power systems, power grid and electrical equipment is safe and reliable operation of the guarantee.
Levels in power plants and substations voltage power distribution equipment, mostly rectangular or circular cross-section of bare wire or stranded wire, which will motors, transformers and various electrical wires connected to, distribution and transmission of electricity. As the bus running, there is tremendous power through, short circuit, under a lot of heat and electric power effect, therefore, must be reasonable selection of bus material, section shape and area to meet the safety requirements of economic operation.
The design according to the typical 330kV power plants and substations electrical wiring diagram of the main methods, according to plant, the relay, static fill device, double busbar substation transformer and the requirements of the measures designed to protect 330KV substation and methods.
Key words: double bus substation 330KV substation protection devices Static Compensation
