Our company has an excellent team to develop induction motors. The economy of induction engine factory application is as follows:
(1) The power station equipped with asynchronous generator does not need dc excitation system, and the investment cost of the power station is low due to the simultaneous installation.
(2) Because there is no collector ring, brush and rotor excitation winding, the maintenance and operation costs are low.
(3) The rotor of the asynchronous generator is the rotor winding similar to the hidden pole and non-synchronous generator, so the general efficiency is higher than the synchronous generator with the same capacity and speed.Under the same water source, the use of asynchronous generators can generate more electricity.
(4) The above economic advantages of the asynchronous generator will be partially offset by the excitation (or additional synchronous capacity or additional capacitors) required by the asynchronous generator.
(5) The size of excitation required by the asynchronous generator is inversely proportional to the rated speed of the motor (that is, proportional to the polar logarithm of the motor). The higher the speed is, the lower the nominal excitation is.
(6) The plant area of the asynchronous generator power station is smaller than that of the synchronous generator power station.
