Introduction of electrical equipment
Small hydropower station (Capacity is 25000 kW and below, voltage level of on grid is below 110 kV) system consists of hydraulic structures, turbine generator set, electrical equipment constitutes.
According to the function of electrical equipment will be divided into primary equipment and secondary equipment.
Primary equipment is used directly in the production, transmission, distribution of electrical power equipment, including generators, power transformers, circuit breakers, disconnectors, bus, power cables and transmission lines, etc., they constitute the main part of the power system.
Secondary equipment are low voltage electrical equipment, they monitoring, control, measurement, regulation and protection for electric power systems and primary equipment condition, including measuring instruments, control of primary equipment, operation monitoring signals, automated control systems, relay protection and automatic safety devices, communication equipment ect.
Secondary equipment connected to form an electrical circuit is called secondary wiring or called secondary circuit,It is to ensure the safety of the power system operation, and reliable power supply.
