Location
Coulomb Wind Farm Huadian Inner Mongolia Huiteng Xile CoulombWind Farm project site is located in Ulanqab City, Inner Mongolia Autonomous Region, within the territory of Coulomb Sumu, Chahar Right Wing Central Banner. The total area of the wind farm is about 53 square kilometers. The site is sparsely vegetated, mostly desert grassland; the terrain around the site is rolling, with an average altitude of about 1430m. 180km to the southwest from Hohhot, the capital of Inner Mongolia Autonomous Region, and 120km to the southeast from Jining, the seat of Ulanqab City Government.
Введение
Coulomb wind farm project planning to install 200MW, once completed, the installed capacity of 134 wind turbines with a single capacity of 1500kW. The wind farm built a 220kV booster station, with 220kV voltage level access to the system. It will make full use of the wind energy resources in Inner Mongolia, improve the monolithic energy structure of Inner Mongolia, protect the environment and reduce pollution, and conserve the limited coal and water resources.
The construction of this project can also enhance the stability of regional power supply, reduce the contradiction of regional power supply demand, increase local tax revenue, improve the living standard of the people in the region, and drive the development of local economy. In addition, the construction of the wind farm can add a beautiful landscape for the local tourism resources, promoting the development of local tourism, economic, social and environmental benefits are very significant.
Integrated Circuit Design
The topography of the wind farm is relatively flat, located in the desert grassland of Coulomb Township in Zhongyu Banner, and the road from Kabul Township, the seat of the Banner Government, to Coulomb Township passes through the wind farm, with a width of about 100m on the west side of the road. According to the different distribution points of wind turbines, 134 wind turbines are distributed on both sides of the flood trench, 57 wind turbines are arranged on the west side of the flood trench, and 77 wind turbines are arranged on the east side.
According to the characteristics of the project, the power collection line between wind turbines is connected by a combination of buried cable and overhead line, and the overhead line is connected when crossing the flood trench, while the rest of the terrain is connected by buried cable.
Secondary section
The electrical control system of wind turbine is based on programmable controller as the core, and the control circuit is composed of PLC central controller and its function expansion module. It mainly realizes the normal operation control of wind turbine, safety protection, fault detection and processing, setting of operation parameters, data recording and display as well as manual operation, and is equipped with various communication interfaces, which can realize local communication and remote communication.
The electrical control system consists of power distribution cabinet, control cabinet, cabin control cabinet, sensors and connection cables, etc. It contains three functions of normal operation control, operation status monitoring and safety protection.The wind turbine monitoring system is divided into a central monitoring system and a remote monitoring system. The central monitoring system consists of local communication network, monitoring computer, protection device, central monitoring software, etc.
The function is mainly to facilitate the wind power plant. The function is mainly to facilitate the centralized management and control of wind turbines by wind power plant personnel. Remote monitoring system consists of central monitoring computer, modem, data transmission media (telephone line, wireless network, Internet), remote monitoring computer, protection system, remote monitoring software.
The function is mainly to allow remote users to view the operation status and historical information of the wind turbine in real time. The local communication network physically connects the wind turbines through cables, fiber optic cables and other media, and the network structure supports chain, star, tree and other structures. The central monitoring system monitors the host computer through fiber optic cable and the connected local communication network to realize centralized management and control of each wind turbine in the wind farm.
Fire detection system
Set up a set of automatic fire alarm control system in the booster substation. The control system adopts bus system, alarm and linkage control common line. The fire alarm controller is set in the main control room, and the fire alarm regional controller is set in the comprehensive office service building. T
he fire alarm controller in the main control room is equipped with a backup manual to start the fire pump, and the fire hydrant button that can directly start the fire pump is set in the comprehensive office service building; fire alarm detection devices are installed in the main control room, relay protection room, battery room, 35kV power distribution device room, power room, main transformer, etc.
When a fire occurs, the fire alarm detection device can automatically send a signal to the fire alarm area controller, and after the fire alarm area controller detects the fire, it can start the related linkage equipment through the linkage control bus according to the pre-set logic. The fire alarm area controller can display the area where the fire occurred, the time and the status of the fire protection system equipment.
In the main channel and important places set up sound and light alarm equipment, when the fire occurs, the fire alarm area controller should be able to start the sound and light alarm equipment to remind and evacuate people in time. Automatic fire alarm control system has a self-test function, normal operation, the regional controller can self-diagnosis of the entire system, when the network or detector failure, you can call the police.
