Introduction of Special Power Grid
First, the power plant and network cabinet cabinet design:
The use of modular power distribution cabinet, surrounded by sealing board, protection class IP22, cabinet four boxes for the punching beam column, free and easy to install a variety of stents. The upper part of the closed control room, both sides open ventilated blinds, Left hinge door, easy to operate the operator overhaul operation. The whole cabinet with special thick 2mm electrolytic steel plate, the molding pickling, baking, spray, and then dry and other processes to ensure that it is not easy to paint, corrosion rust. U-shaped channel support, so that the entire cabinet can be firmly on the cable groove

Second, the power plant dedicated grid cabinet busbar (bus):
All the busbar connection surface all tin, to ensure reliable contact, were marked with yellow, green, red, black four
Color mark, to show phase sequence, shiny bright.

Third, the power plant dedicated and parallel cabinet device
1, the power plant-specific and main counters can choose:
(1) The original IC-NT module imported from Czech Comay is used to realize all-digital speed adjustment and automatically adjust the unit speed. When the machine is running, the active load is automatically distributed, and the active power imbalance is less than ± 3%. , So that the project is more convenient to use.
(2) using the original British original imported 7510 module, linkage to achieve full digital speed, automatically adjust the unit speed, automatic operation and machine active load distribution, active imbalance ≦ ± 2%; More simple.
(3) the use of Denmark DEIF original imported AGC232 module, linkage to achieve full digital speed, automatically adjust the unit speed, and machine operation automatically allocated active load, active imbalance ≦ ± 2%; Simpler, more user-friendly logic control, powerful, follow-up project to facilitate the expansion, but the use of the professional requirements of engineers is higher. Is the largest international power plant management and control unit of the first suppliers.
Manual closing / stop / automatic closing; set manually with a protective cover with light button, must be in the same period when the indicator light can be operated to close;
3, This section of power plant-specific network counters Frequency: synchronous automatic tracking, the use of automatic frequency, phase tracking, automatic synchronous closing electronic automatic synchronizer, the unit speed control system in the normal reaction state, when the unit to the rated speed After 3 seconds to complete the parallel process, without any operator adjustments.
According to the different power generators, according to the size of the average proportion of the total load distribution from no-load to full load automatic load distribution error rate can be controlled within 2% with a PID Closed-loop control link, when the load fluctuates greatly, it can increase the oil quantity before the speed change, instead of the hysteresis characteristic that the traditional speed control system needs fueling after the speed dropping.
4, automatic start: the controller set of measurement, control, protection, and many other functions into one, fully meet the needs of self-starting control unit, with communication capabilities, the data can be uploaded;
5, this section of the power plant dedicated network cabinet to prevent the collapse of the system: the system in software and hardware design on the use of the principle of division of labor, software, simplification, only a few menu parameter settings; hardware modular, Speed ​​module, display operation module, unit start module, unit communication module, unit load sharing module, in the structure and the electrical circuit does not interfere with each other to improve the product reliability and cost performance, to prevent system collapse;
6, automatic and machine: automatic control frequency and phase and bus the same, automatically issued a closing signal, the unit parallel operation;
7, soft unloading: When the load is lower than the rated power of a single unit or the sub-gate signal is received instruction, the unit to transfer the load to a minimum, the parallel switch sub-gate, to achieve unit soft unloading, maintenance crew / no-load operation 3-5 minutes after the automatic shutdown;
8, soft loading: When the load exceeds the rated unit power limit or received a closing signal command, the unit automatically starts, automatically and machine, the load slowly increased to the system power requirements, to achieve unit soft loading;
9, this section diesel generator and cabinet has perfect function:
Ø Control and automatic starting, testing and stopping procedures for diesel engines;
Ø Manual start and stop;
Ø Automatic and manual control of voltage and frequency;
Line voltage and phase voltage measurement;
Ø Line current measurement;
Ø Frequency measurement;
Ø Generator control, diesel engine and unit control panel heater and accessories.
Ø battery, charger and control;
Operating instructions for diesel engines
Ø Generator circuit breaker closing
O Diesel locking
Ø Power input
Ø Alarm:
Diesel engine is not ready to start
Ø Cooling water level is low
Ø Fuel oil level is low
Ø Battery voltage is low
O Electrical faulty parking
Ø Diesel engine fails to start
O Diesel engine fails to stop
Ø Generator under voltage
O Diesel engine parking together with pre-alarm
Ø Low lubricating oil pressure
O Diesel engine overspeed
Generator failure
Ø Have internal clock, can record unit important time and its occurrence time, can record running schedule (can not reset)
Each alarm and display function shall be capable of providing a remote control display and shall provide an alarm with the 'answer' button on the unit control panel for the corresponding alarm function;
