XES-01C-400 Fully-automatic generator integrated control cabinet
- Product description: XES-01C-400 series generator set integrated control screen is specially designed to improve the power generation quality and automation of low-voltage units in hydropower stations. This control screen is equipped with one screen cabinet for one unit. It is simple, convenient and highly integrated. It has "excitation (or double excitation), double protection, automatic quasi-synchronization (or double synchronization), water machine control, automatic power adjustment, power Parameter measurement, temperature measurement, water level monitoring display, opening display and electrical parameter display. " After the control panel is put into operation, it can realize unattended and less attended, and the level of product automation reaches the domestic advanced level. This product is mainly used for rated voltage
1 Overview XES-01C-400 series generator set integrated control screen is specially designed to improve the power generation quality and automation degree of low-voltage units in hydropower stations.
励磁 （或双励磁） 、 双 保护 、自动 准同期 (或双同期） 、水机控制、功率自动调节、 电参数 测量、 温度测量 、 水位监测显示、开度显示及电参数显示 ”。 This control screen is equipped with one screen cabinet for one unit. It is simple, convenient and highly integrated . Parameter measurement, temperature measurement , water level monitoring display, opening display and electrical parameter display . " After the control panel is put into operation, it can realize unattended and less attended, and the level of product automation reaches the domestic advanced level. 额定电压400V、单机容量 15 00kW及以下 的水轮发电机组。 This product is mainly used for hydro-generator units with a rated voltage of 400V and a stand-alone capacity of 1 500kW .
The control screen hardware and software adopt modular and structured design, which is not only convenient for the expansion of equipment, but also conducive to the increase of functions and the expansion of the system.
This control screen contains the following functions :
1) Unit double protection function;
2) Unit dual synchronization function;
3) Double excitation function of the unit;
4) Automatic start and stop; manual start and stop;
5) Multi-mode operation, press the water level switch; press the potentiometer; press the water level sensor; automatically adjust the power;
6) Automatically start and stop according to the water level, and automatically adjust the power of the unit according to the water level;
7) Fully automatic start-up and automatic synchronization grid connection;
8) Unit measurement function; unit electrical parameters, temperature, opening degree;
9) conventional manual operation and conventional instrument monitoring;
10) It can be connected to a computer to form a network to complete centralized management, centralized control, data recording, query printing, etc. of the power station, and it can also be connected to the dispatching center to achieve unattended and less attended duty
11) Manual and automatic disturbance-free switching;
2 system structure The above figure is the system network structure diagram. The equipment in the dotted line is optional. The computer is connected to one or more unit integrated control screens, which can form a network to achieve the purpose of unattended and unattended. The computer can be placed in a hydropower station or a remote control center. When the computer is placed in a remote control center, optical fiber or other wireless communication networks are required.
3.1 Primary primary equipment 1) Circuit breaker: DW15 or DW45 series pre-stored energy-saving circuit breakers are installed vertically.
2) Isolating knife gate: HD13BX series knife switch is used.
3) Current transformer: LMZJ type is used to measure and protect three CTs.
4) Microcomputer excitation regulator; constant power factor operation.
5) Excitation transformer: It is only available when the unit is brushed. It is configured according to the unit parameters.
