Automatic generator control cabinet
After a few generators machine are combinet together.it just likes that quite a high power generator supply power to the load.It can be determined by the size of the load, and open several machines (units in 75% of the rated load - the case of that the lowest fuel consumption),so as to achieve the purpose of savings of gas and reducing the cost of the generator.Achieve uninterruptible power supply to protect the normal production plant.When the unit conversion are using standby unit ,and it can be incorporated into the operating system, and then load all into the standby unit, and then discontinue the operation of the unit, it does not need to stop the power.Multipling units operating in parallel, a sudden increase in load current can be shared equally by the impact of multiple units, each unit reduce voltage and make frequency stability, prolong the working life of the unit.

Screen Design
A modular power distribution cabinets is surrounded by closure plate with protection class IP40, the cabinet frame for punching four beams, free and convenient to install all kinds of support.Upper part belongs to the enclosed control room, ventilation louvers on both sides of the opening hole, left hinged door for easy operator maintenance operations. The whole group electrolysis enclosure with 2mm thick steel plate special, after forming pickling, drying Bureau, spray, then dried and other processes, to ensure that its difficult to Paint Falling off rust corrosion. U-shaped channel with a support base, so that the entire cabinet can stand secure in the cable trench.

Busbar
All busbar are connected all the tin surface, to ensure reliable access, were marked with yellow, green, red, black four color,more than that coded mark show the phase according to sequence, is shiny.

Self - start and stop
1.When the mains fails, choosed as priority promoter generator starts and automatically synchronize to ATS cabinet (provided by the Party) transmission, and then send the power to the load by ATS cabinet cabinet.
2.When the output load exceeds the total amount of the total parallel generator set power more than 70%, parallel cabinet will automatically output the start signal, the next generator set up and switch on automatically synchronized to the power transmission grid.
3.When the total load is less than the total output of the generator set in parallel to power 25% or less, parallel cabinet opening will be issued with stop signal. The unit will automatically shut down one by one sub-gate and delay until the stop of the priority unit .
4.When the mains supply is normal, ATS automatic reversal of the mains power supply cabinet, parallel cabinet will shut down one by one sub-gate and delay.

Automatic tracking, synchronization
Using automatic frequency, phase tracking, automatic synchronization closing electronic automatic synchronizer unit governing system under normal reaction condition, when within 3 seconds after the crew reached the rated speed parallel process can be completed without any adjustment operator .

Automatic load distribution
With no difference in the use of automatic load distribution system, fully electronic, highly responsive, high-paced Etc.According to the different power generating units, the average percentage of the total load distribution by size.From no load to full load is automatically assigned deviation rate.which can be controlled within 10%.With PID closed-loop control link, when the load fluctuations can increase the amount of oil in advance before the speed changes, unlike generally conventional speed control system which it need to speed down before refueling hysteresis ,so that can make the grid habe a better performance.

Protective functions
1.Unit fault linkage Trip: If the unit in operation due to high water temperature and other issues shutdown, it will be linked in parallel switch tripped while avoiding save power and drag the other operating units .
2.The save power protection: it can contribute to the running off control system when the engine or the control unit of the system works failure ,and it will automatically cut off the unit, then the concurrent sound and light alarm.
3. Over-current protection: When the unit is running beyond its rated load carried by 80% -100% (adjustable)), the control system will automatically cut off the unit, and then shows the concurrent sound and light alarm.
4.Parallel cabinet panel device has 360 degree rotation pointer synchronization table, synchronized lights and multi-loop frequency, voltage trimming, the emergency manual and the car can be observed with the unit and adjust the frequency difference between the busbar voltage. In parallel to achieve manual.
5.And it has a on a prominent position on the cabinet disk drive self-locking red emergency stop button, when the duty officer found unprepared emergency, you can press this button, the unit will stop instantly opening and exit parallel system.
