In synchronous motor excitation system. The main task of the regulator is the realization of the automatic control of the excitation circuit. In order to achieve the adjustment value of synchronous motor excitation current expectations. Concrete said. The effect of excitation regulator can be summarized as the following. 1. According to the generator load automatically adjusting excitation current. In order to maintain the voltage of the host or a point in the system voltage to achieve the desired level. 2. Improve the static stability of the power system operation and the transmission capacity of the transmission line. When the system is subjected to some degree of small signal, the controller can automatically adjust the host field current and synchronous motor can quickly return to the front of the disturbance of running state. At the same time also can improve the static stability of the synchronous motor ability, expanding the scope of the static stability, partial, & gt; 90. In order to increase the ability of power system transmission power. 3. Change lane running the dynamic stability of power system. When the system suffered some degree of big interference, sudden short circuit (for example, systemIncluding the asynchronous motor starting RongTong larger)Voltage of the machine in serious decline. Arc line excitation regulator to host to improve the dynamic stability of the system. As another example, system load rejection. The voltage of the machine rapidly rising, and even could reach the rated voltage of 1. 3 -1. 4 above, regulator to host magnetic reducing with arc line, in order to prevent the motor for overvoltage damage the insulation. 4. Realize the synchronous generator in parallel between a reasonable allocation of reactive power. Excitation regulator of an important role, is to make parallel operation of the synchronous generator adjusts according to certain rules between reasonably share the total reactive power system needs. 5. According to the requirements of the power system, the realization of excitation control of synchronous generator different way. According to the requirements of power system, synchronous generator excitation regulator to realize: constant excitation control, constant reactive power control and constant power factor control under different ways, such as adjusting excitation current, to power system operation performance is good,. The purpose of and the economic benefit from. 6. Improve sensitivity and reliability of the relay protection is installed it with time. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
