GDYWT series high oil pressure microcomputer governor, which adopts the latest achievements of programmable technology, modern hydraulic technology and digital technology. Simple structure, reliable operation, excellent performance, convenient maintenance and high cost performance. Compared with the traditional low oil pressure (2.5/4.0Mpa) governor, the use of high oil pressure (16Mpa) has significant technical and economic advantages: high working oil pressure, so small size, light weight, less oil consumption, The layout of the power station is convenient and beautiful.
Using a bladder-type accumulator to store energy, the nitrogen gas in the bladder does not contact the hydraulic oil, and the oil quality is not easy to deteriorate; It not only eliminates the gas supply and oil level adjustment work during the operation of the power station, but also saves the high-pressure gas system and the corresponding auxiliary workshop.
◆Measure the frequency of the unit and the grid, and realize the frequency adjustment when the unit is no-load and isolated;
◆The frequency of the unit automatically tracks the frequency of the power grid when there is no load, which is convenient for fast grid connection and saves water and energy;
◆ The governor has enough stored energy, which can ensure reliable shutdown even if the generator and the grid have no power supply at the same time, avoiding the speed of the unit, which is safer;
◆It can be equipped with automatic resetting, automatic braking, automatic closing of the main valve and energy supply;
◆Manual start and stop, increase or decrease load and run with load;
◆Unconditionally and undisturbed switch between automatic and manual;
◆When an electrical fault is detected, it can be automatically switched to manual operation and the load will be fixed in the state before the fault.
◆ Adopt imported Mitsubishi high-reliability programmable logic controller (PLC), small in size, strong in anti-interference ability, and the mean time between failures is more than 300,000 hours;
◆Using software frequency measurement to meet the requirements of frequency measurement timeliness and frequency measurement accuracy, stable control when tripping and load shedding, avoiding flying, and making the unit safer and more reliable; span>
◆ Collect the main parameters and operating status of the governor such as machine frequency, net frequency, guide vane opening, manual, automatic, etc., and display it on the display; screen to adjust the operating parameters of the governor;
Adopt PID intelligent control, with good stability and adjustment accuracy and quality, to avoid too much noise.
