External-control pole-changing power generation system

Abstract

The invention discloses an external-control pole-changing power generation system. The external-control pole-changing power generation system is composed of an excitation coil 1, an external annular magnetic conductor 2, an output coil 3, an internal output magnetic conductor 4, an active magnetic control system lidesheng 14 and the like. The built-in control information of the active magnetic control system lidesheng 14 is respectively output through a first active magnetic control system lidesheng control port 9, a first input port 7 and a second active magnetic control system lidesheng control port 13 for supplying power to the excitation coil 1 through a second input port 10, the excitation coil 1 generates an N / S variable polar magnetic field after obtaining electricity, the motor coil 3 is cut by the N / S variable polar magnetic field generated by the excitation coil 1 and a rotor synchronously, the motor coil 3 generates AC voltage through cutting magnetic lines of force, and electric energy is output through a first output port 15 and a second output port 16 respectively. Therefore, the external-control pole-changing power generation system achieves the purpose of adjusting stability of the output voltage in a pole-changing manner by changing rotating speed in a cycle.

Description

technical field [0001] The invention relates to an externally controlled pole-changing power generation technology for multi-field applications such as active magnetism, and in particular to a device that uses an outer annular magnetizer to control the forward and reverse of the wire-wrapped current and the size of the wire-wrapped current; And water power generators and power generation devices using unequal speed drives (referred to as "external control pole-changing power generation system"). Background technique [0002] At present, frequency conversion technology cannot be applied to generators because the frequency of the power grid is a fixed value. New energy wind turbines and hydropower generators cannot uniformly drive generators due to wind speed and flow velocity, resulting in unequal power generation and unstable voltage fluctuations; The difference in power generation is large when the machine speed ratio is large; the cost of multi-pole low-speed and direct-dr...

[0002] At present, frequency conversion technology cannot be applied to generators because the frequency of the power grid is a fixed value. New energy wind turbines and hydropower generators cannot uniformly drive generators due to wind speed and flow velocity, resulting in unequal power generation and unstable voltage fluctuations; Large machine speed ratio and large difference in power generation; multi-pole low-speed and direct-drive generators are expensive, the process structure requires high precision, and permanent magnets are easily affected by other magnets, making it difficult to replace demagnetization and loss of magnetism
