Description
Product details:
Definition: Many electrical equipment are based on the principle of electromagnetic induction work,
such as transformers, motors, etc., they rely on the establishment of alternating magnetic field in order to
carry out energy conversion and transfer, in order to establish alternating magnetic field and induction flux
and the electric power required is called reactive power.
All electrical equipment with electromagnetic coils, to establish a magnetic field, it is necessary to consume
reactive power. Without reactive power, the motor will not turn and the transformer cannot change voltage. So reactive power is by no means useless power.
Action: Under normal conditions, electrical equipment not only obtains active power from the generator,
but also needs to obtain reactive power from the generator. If reactive power is in short supply in the power grid, the
electrical equipment will not have enough reactive power to establish normal electromagnetic fields. Therefore, the electrical
equipment cannot work at the rated condition, and the terminal voltage of the electrical equipment will
decrease, which affects the normal operation of the electrical equipment.
The reactive power output of the generator is related to the excitation current.
What is excitation?
A DC magnetic field is required for the operation of the generator. The DC current that generates this field,
called the excitation current, is supplied to the rotor windings of the synchronous generator.
What is an excitation system?
The whole supply of excitation current line and equipment device called excitation system.
■ The composition of the excitation system mainly includes
■ Excitation control unit
■ Excitation power unit
■ Power system stabilizer PSS
■ Limiting and protecting circuits
■ Power transmitter and load compensation
