Power grid and dedicated counters Introduction
First, the power plant and network cabinet cabinet design:
The use of modular distribution cabinet, surrounded by sealing plate, protection class IP22, The four box frame for the punching column, can be free to facilitate the installation of various stents.The upper part of the closed control room, both sides open a ventilation louvres, left hinge door, convenient operator maintenance operation. 2mm Electrolytic steel plate, forming pickling, baking, spray, and then dry and other processes to ensure that it is not easy Diaoqi, corrosion rust. UType channel support, so that the entire cabinet can be safely standing on the cable trench

Second, the power plant-specific and network counters bus (bus):
All the busbar connection surface of all tin, to ensure reliable contact, respectively marked with yellow, green, red, black four
Color mark, to show phase sequence, shiny bright.

Third, the power plant and network counters and machine-specific equipment
1, The power plant special-purpose grid main controller may choose:
(1)Czech imports using the original Comay IC-NT Module, linkage to achieve full digital speed, automatically adjust the unit speed, parallel operation and automatic allocation of active load, active imbalance ≦± 3%; The use of more engineering design ,So that works more convenient to use.
(2)Using the original British original import 7510Module, linkage to achieve full digital speed, automatically adjust the unit speed, parallel operation and automatic allocation of active load, active imbalance ≦± 2%; The use of simple design of human nature Hua ,So that the use of more simple.
(3)Using Denmark DEIF Original imported original AGC232Module, linkage to achieve full digital speed, automatically adjust the unit speed, parallel operation and automatic allocation of active load, active imbalance ≦± 2%; The use of simple design of human nature, the use of more simple, more user-friendly logic control, powerful, easy to extend the follow-up project, but the professional requirements of the use of engineers is high, the international power management and control unit of the first supplier.
2, Power plant and dedicated counters closing method: manual closing /stop /Automatic closing; manually set with protective cover with light button, must be in the same period indicator light can be operated when closing;
3, This section of power plant-specific network counters FM: 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 3Seconds to complete the parallel process, without any operator adjustments.
Load allocation: active load distribution, reactive load distribution all automatic, according to the different power generators, according to the proportion of the average size of the total load distribution from the no-load to full load automatic load distribution deviation rate can be controlled 2%Within 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 as one, fully meet the needs of self-starting control unit, with communication capabilities, the data can be uploaded;
5, This power plant dedicated network counters to prevent system crashes: the system software and hardware design using the principle of division of labor ,Software simplification, only a few menu parameter settings; hardware modular ,Voltage control module, speed control module, display operation module, unit startup module, unit communication module, unit synchronous load distribution module, in the structure and electrical circuit without interference, improve product reliability and cost performance, prevent system collapse;
6, Automatic and machine: automatic control frequency and phase with the same busbar, automatically send closing signal, the unit parallel operation;
7, Soft unloading: When the load is lower than the rated power of a single unit rated power or access to the sub-gate signal, the first transfer load to the minimum, the parallel switch sub-gate, to achieve soft unloading unit, unit maintenance /No-load operation 3-5Minutes after the automatic shutdown;
8, Soft load: When the load exceeds the rated power of a single unit or received a closing signal command, the unit automatically starts, automatic and machine, the load slowly increased to the system requirements of power, to achieve the unit soft loading;
9, This diesel generator and the cabinet has a perfect function:
O Control and diesel engine automatic start, test and stop procedures;
O Manual start and stop;
OVoltage and frequency of automatic and manual control;
O Line voltage and phase voltage measurement;
O Line current measurement;
O Frequency measurement;
ØGenerator control, diesel engine and unit control panel heater and accessories.
Ø Batteries, chargers and controls;
Ø Diesel engine operating instructions
ØGenerator circuit breaker closing
Ø Diesel lock
Ø Power input
Ø Call the police:
Ø Diesel engine is not ready to start
ØCooling water level is low
Ø Fuel oil level is low
Ø Low battery voltage
Ø Electrical faulty parking
Ø Diesel engine fails to start
ØDiesel engine failure parking
Ø Generator under voltage
Ø Diesel engine parking together with pre-alarm
Ø Low oil pressure
Ø Diesel engine overspeed
Generator failure Ø
Ø There is an internal clock, can record the unit important time and its occurrence time, can record the running schedule (can not be reset)
Each alarm and display function should be able to provide remote control display, should be for the corresponding alarm function, in the unit control screen with 'answer ' Button siren;
