The solution to the problem that the power offset voltage is higher than the normal value is as follows.
1. Replace the regulator. The voltage regulator fails, causing the generator voltage to be too high. It is necessary to replace the voltage regulator with a new one depending on the generator model.
2. Reduce speed. By reducing the opening of the turbine hydrofoils and lowering the rotational speed, the voltage can be reduced.
3. Adjust the air gap. The voltage is too high due to the excessive air gap in the shunt reactor core. It is necessary to change the thickness of the reactor core gasket and adjust the core air gap.
4. Repair the magnetic field rheostat. A short circuit in the magnetic field rheostat will cause voltage regulation to fail. It is necessary to find the short circuit point and repair the magnetic field rheostat.
If a generator generates more reactive power, it will lose less active power, right?
Causes:
1 Rheostat failure: If The power generated by the generator is too high, this is probably due to a failure of the magnetic field rheostat, which cannot stabilize the output voltage. It is necessary to check and replace the broken rheostat in time, otherwise it will affect the normal use of the. car.
2. Generator failure: If the brushes and coils of the generator fail, the power supply current to the generator will be unstable, for example if the voltage is too high or too low. It is recommended to go to the 4S store. to have the generator fault checked.
3. The speed is too high. Treatment: Reduce the opening of the turbine water guide film and reduce the speed.
Error
The amount of active power generated by the generator is determined by thetransmission power of the main motor.
The amount of reactive power generated by the generator is determined by the excitation current of the generator
As long as the transmission power of the main motor n is not changed (i.e. the hydrofoil angle of the turbine or the throttle opening of the diesel engine)
The active power generated by the generator will not change< /p>
The premise of the above conclusion is that the generator operates in parallel with the large power grid
In fact, only the generator operates in parallel with the grid
< p>can the reactive power it generates be adjusted independently
