Large diesel generators lease the equipment to convert electricity into light for people’s lives and work. The symbol for active power is p, and the units are watts (W), kilowatts (kW), and megawatts (MW).
Large diesel generator leased reactive power is abstract, it is used for electric and magnetic field exchange in circuits, and for magnetic field establishment and maintenance in electrical equipment. It doesn’t do external work, it gets converted into some other form of energy. All electrical devices with electromagnetic coils consume reactive power to establish a magnetic field. It is called “reactive power” because it has no effect on the outside world. The symbol of reactive power is Q and the unit is Var or kVar.
Large diesel generator rental reactive power is far from useless power, it is very useful. The motor needs to establish and maintain a rotating magnetic field to make the rotor rotate and thus drive mechanical motion. The rotor magnetic field of the motor is established by obtaining reactive power from the power supply. The transformer also needs reactive power to generate a magnetic field in the transformer’s primary coil and to induce a voltage in the secondary coil. Therefore, without reactive power, the motor will not turn, the transformer will not transform, and the AC contactor will not attract.
In normal cases, electrical devices need to obtain both active and reactive power from the power supply. If the reactive power in the grid is insufficient, the electrical equipment will not have enough reactive power to establish a normal electromagnetic field. Then, the electrical equipment will not be able to work under rated conditions, the terminal voltage of the electrical equipment will drop, thus affecting the normal operation of the electrical equipment. The leased reactive power of large diesel generators has certain adverse effects on power supply and consumption, mainly manifested in:
1. Reduce the output of active power of the generator.
2. Reduce the power supply capacity of transmission and transformation equipment.
3. resulting in the increase of line voltage loss and power loss.
4. resulting in low power factor operation and voltage drop, so that the capacity of electrical equipment can not be fully utilized.
The reactive power provided by power generation equipment and high voltage transmission lines is far from meeting the needs of loads. Therefore, some reactive power compensation devices should be set up in the power grid to supplement the reactive power, so as to ensure the user’s demand for reactive power, so that the electrical equipment can work under the rated voltage. This is why the grid needs to install reactive power compensation devices.
