INTEGRATED COMMUNICATION SCHEDULING SCHEME FOR WIND POWER GENERATION

1、 OVERVIEW OF CURRENT SITUATION

With the implementation of national wind power industry policies and the development of wind power technology, China's installed wind power capacity has become among the top in the world. With the deepening of wind power development, remote mountainous areas, high-altitude areas, and offshore wind power are becoming the main directions for wind power development in China. Wind farms are generally widely distributed in areas with abundant wind resources, such as mountains, deserts, plains, and offshore areas, where transportation is inconvenient, terrain is complex, and the area is vast. In remote areas, onshore wind farms generally extend tens or hundreds of kilometers, while offshore wind farms often extend hundreds of square kilometers. The distance between points is relatively long, reaching several kilometers or even tens of kilometers. At the same time, the on-site environment may also have characteristics such as ultra-high temperature, ultra-low temperature, humidity, acidity and alkalinity, corrosion, high dust, and high electromagnetic interference.

However, in these areas, the operator's network signal coverage is insufficient, resulting in on-site personnel being unable to communicate effectively with the wind farm monitoring center personnel through effective communication methods.

In addition, the wind tower is a pure metal cylindrical structure with smooth inner walls; Internal radio signals will undergo strong reflections, causing serious interference to the transmission of wireless signals from mobile phones and walkie talkies. As a result, during on-site inspections, the operation and maintenance personnel were unable to establish good communication with the wind farm monitoring center, and the wind farm monitoring center was also unable to issue timely and effective instructions to the on-site personnel of the wind turbines and carry out control.

2、 REQUIREMENTS FOR WIND POWER DISPATCH COMMUNICATION SYSTEM:

1). Transmission distance requirements

Meet the wide communication transmission distance of offshore/onshore wind farms.

2). Adapt to harsh environments

① Adapt to harsh EMC/EMI environments.

② Capable of protecting against sand, dust, moisture, acid, alkali, water vapor, mist, and vibration environments.

③ Can work normally at extremely low or high temperatures.

3). Meet the requirements of reliable redundancy

In case of emergencies, the system and lines need to have redundancy capability to resume operation in a very short period of time.

4). Support multi network integration

Due to the fact that wind turbines are often installed in remote locations, the dispatch system needs to support various possible network connections (such as power private networks, IP networks, 4G/5G networks, and satellite communications) to ensure smooth communication.

5). Easy expansion and advanced technology

With the increase in the number of wind turbines, a very convenient expansion system is needed, and the technology needs to be able to meet the communication needs of the next 5-10 years.

3、 SHOLLPER TECHNOLOGY WIND POWER FUSION COMMUNICATION DISPATCH SYSTEM

The Xiaoben Technology Wind Power Integrated Dispatch Communication System is a highly integrated integrated dispatch management system that can not only exist as a standalone telephone system, but also as a centralized control center management platform (supporting the linkage of multiple systems such as video surveillance, voice, broadcasting system, radio station, distress alarm, GIS geographic information, etc.). In the past 10 years, this system has been widely used in many wind power enterprises at home and abroad and has been unanimously recognized.

This system consists of a dispatch host deployed in the control center, a dispatch console, and industrial telephones/stations, explosion-proof telephones/stations, IP telephones, intercom terminals, cameras, broadcasting systems, intercom systems, etc. installed in various wind turbines and administrative office areas. All devices and terminals can be deployed based on IP networks, and in case of emergencies, dispatch machines and consoles can be quickly deployed in the network, including on power rescue command vehicles, to ensure that scheduling and control can be carried out wherever there is network access.
