Analysis And Design Of Control Protection Circuit Of Synchronous Motor

Synchronous motor is an important part of power supply for large chemical enterprises.so the protection control of synchronous motor is related to the stable operation of enterprise electrical equipment.Therefore,the control of synchronous motor has become the most important part of enterprise electrical work.Due to the increase and optimization of the auxiliary machine and chain system of the transmission equipment such as large compressor,the control of synchronous motor is higher.In this context,the control system of the synchronous motor control circuit is designed by using the electromagnetic induction technology and the computer and other technologies.This control system adopts the mature excitation control technology and computer communication technology and relay control technology to design the actual synchronous control protection system.Through the sensor acquisition of main electric parameters such as current,voltage microcomputer measurement and control protector for Identify and calculate the value information of the obtained parameters,and pass the interface of the communication management system,the real-time running status monitoring platform for data transmission to the background computer.When the abnormal data alarm occurs,the microcomputer measurement and control device will display the alarm information to the background of the microcomputer through the software and issue an alarm message or a trip output,thus reminding the substation duty duty work to handle the alarm information in a timely manner.The alarm content on the device is also stored and recorded..In order to ensure the whole system safe and reliable operation,the dynamic monitoring of the whole synchronous machine is realized.
