The methods of improving the performance of generator excitation control system are described briefly
The new achievements of opto-mechatronics are widely used in the control system of modern generator. From simple hand control to a series of new technologies such as programmable controllers or microprocessors. Redundancy backup from single machine to multiple machine to ensure the reliability of the power supply system. Improving generator excitation control system is the most economical and effective way to improve generator performance.
Microprocessor or programmable special controller. The special controller using computer technology makes the generator use process more flexible, more reliable operation, summed up mainly has the following modes: single machine automatic control function: according to the situation to set the self-start generator, low oil pressure, high water (oil) temperature, overspeed alarm and stop protection. The single machine starts automatically and works with the ATS to implement automatic switching.
Detects the mains indicator. When the mains is abnormal, the generator automatically starts and automatically supplies power to the load in coordination with the ATS. The mains supplies power first. Once the mains returns to normal, it will automatically switch to mains, and the generator will stop automatically after delayed cooling. Control of two or more machines: according to the running state of a single machine, so that the two are mutually standby, for multiple machines according to the load situation, start the generator and run or unline, reasonable load distribution.
With a remote control interface, in order to complete the remote control, remote communication, telemetry, remote adjustment that is "four remote" function. In the generator control system with Rs232/485 communication interface, the use of currently commonly used microcomputer can be used to monitor the generator, and the generator remote start, remote control normal shutdown, remote control emergency shutdown, remote control fault reset, transmission of its voltage, current, frequency, oil pressure, water temperature, battery voltage and a variety of physical quantity signals. The generator uses digital display. The current, voltage, frequency, speed, oil pressure and water temperature of the generator are changed from the original mechanical instrument to the digital display direction, so as to enhance the reliability and visibility of the auxiliary device of the generator.
