The speed regulation system of gas generator set is used in many industries. It is the leader of modern speed regulation system and has functions that similar products do not have. It can be widely used mainly because of its system performance, which is mainly reflected in:
The power circuit is simple and reliable. Because the motor torque direction is independent of the winding current direction, that is, only one phase winding current is required, so the power supply circuit can realize one power switch per phase. In contrast, the motor winding needs to flow bidirectional current, while the power supply circuit of the power supply inverter needs two power devices per phase. Therefore, the speed regulation system of gas generator set needs less power components than PWM inverter circuit, and the circuit structure is simple.
From the electromagnetic structure of the motor, each winding and magnetic circuit are independent of each other and produce electromagnetic torque within a certain range of shaft angle. Different from the general motor, the rotating magnetic field is generated under the joint action of each phase winding and magnetic circuit, so that the motor can operate normally.
From the perspective of control structure, each phase circuit supplies power to one phase winding and generally works independently of each other. It can be seen that when the single-phase winding of the motor or the single-phase circuit of the controller fails, just stop the operation of the phase, and the total output power capacity of the motor is reduced except that there are no other obstacles.
Many controllable parameters and good speed regulation performance. According to the operation requirements of the motor and the situation of the motor, different control modes and parameter values can be adopted to make it run in a good state (such as high output and high efficiency), and specific curves of various functions can also be realized. For example, the motor has exactly the same four quadrant operation capacity, with high starting torque and load capacity curve of series excited motor.
The system is a very high-speed control system. This is because on the one hand, the motor winding has no copper loss; On the other hand, the motor has many controllable parameters and is flexible and convenient. It is easy to realize optimal control in a wide speed range and different loads. Therefore, the speed regulation system of gas generator set can meet various requirements through self-regulation, and can meet various special application requirements through electromechanical unified coordination design.
