发电机原理及其控制

1、-Sunny Mao u Electrical Fundamentals u Generator principle u Voltage and Synchronization control u Protective relays and breaker control If the circuit is complete, the voltage will cause a current to flow. When a conductor is passed through a magnetic field, a voltage is produced. The main stator c

2、onsists of stationary conductors (armature). The main rotor is a large rotating magnet (field). Conductors moving in reference to a magnetic field = Voltage Active Power (kW) eventually produces some tangible result such as heat or light. Reactive Power (KVAR) surges back and forth between the sourc

3、e and load. This power produces alternating magnetic fields in devices. Apparent Power (kVA) is the vector sum of active and reactive power. Relationship between active and apparent power: Power factor = active / apparent. RPM = Frequency X60 Pairs of pole So if you have a prime mover that runs at 1

4、500 RPM and you wanted 50 Hz, you would need a generator with how many poles? = 2 pairs 50 Hz X 60 1500 RPM Y Turbine generator（D-G-7001） Y Turbine generator（D-G-7002） Y Diesel emergency generator（D-G-7101） Y Typhoon generator (D-TG-01) l D-G-7001/D-G-7002. 3300 VAC, Three phases, 50Hz, 4.076 Meg Wa
