Power factor of hydraulic power generator

Introduction The power factor of the hydroelectric generator is that the generator has a rated active power of 100 kW and the rated power factor is 0.8. The rated capacity is 100/0.8 = 125 kVA and rated power.

Power factor of hydraulic power generator

Your generator has a rated active power of 100 kW and a rated power factor of 0.8. The rated capacity is 100/0.8 = 125 kVA and the rated current is 125/0.4/1.732 = 180.4 A (calculated at a rated voltage of 400 V).

When the generator is working, the capacity (current) cannot exceed the limit. It can be seen that the higher the power factor value when the capacity remains unchanged, the lower the reactive load, the higher the active load. load, and you can receive more benefits (without evaluating reactive power).

Of course, the higher the power factor, the better. It should generally not exceed 0.95. Too high a power factor can easily cause the generator to lose synchronization.

The internal dual water cooling generator adopts water, water and air cooling methods. The stator and rotor windings of the generatorur adopt internal water cooling, and the stator core and end structure adopt air cooling. The cooling water for the stator windings has one water channel for each half-coil. The water inlet is at the excitation end of the stator and the water outlet is at the machine end. The stator connection pipe is also water-cooled, and the water inlet and outlet of each water channel are connected by polytetraethylene pipes. The rotor winding cooling water path has two rows per rotor slot. Each row of spools is a path of water that enters at the bottom of the thread bin and exits at the top of the bin. water channels are connected to insulated water pipes. The main inlet and outlet pipes are made of anti-corrosion and anti-magnetic stainless steel pipes. Cooling water enters the rotor through the excitation end et flows along the hollow axis in the center of the rotor. When the cooling water passes through the end water collection box and the water inlet pipe, it flows to the rotor winding and flows out. the rotor water outlet pipe and the water outlet device. Cooling air is supplied by a fan installed on the rotating shaft of the generator and forms a closed circulation system with the air cooler. Cold air is driven from the end cover air inlets at both ends by installed axial fans. at both ends of the rotating shaft and passes through the surface of the rotor and the stator. The iron core adopts a two-inlet, two-outlet radial ventilation method.
