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 for energy storage, 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 grid at 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 at the same time, avoiding the speed of the unit, which is safer;
◆Optional function of folding water automatic reset, automatic braking, automatic closing main valve and energy supply;
◆Manual start and stop, increase or decrease load and run with load;
◆ Automatic and manual switching between unconditional and undisturbed;
◆When an electrical fault is detected, it can be automatically switched to manual and the load will be fixed in the state before the fault.
◆ Adopt imported Mitsubishi high reliability programmable controller(PLC), small size, strong anti-interference ability, MTBF of more than 300,000 hours;
◆Using software frequency measurement, which can meet the requirements of frequency measurement timeliness and frequency measurement accuracy, stable control when tripping and load shedding, avoid flying, and make the unit safer and more reliable; span>
Collect the main parameters and operating status of the governor such as machine frequency, network frequency, guide vane opening, manual, automatic, etc., and display it on the display screen; it can be displayed through the display The operating parameters of the governor are adjusted on the screen; PID intelligent control is adopted, which has good stability, adjustment accuracy and quality, and avoids too much noise.
