Remote monitoring solution for wind power generation equipment

With the gradual reduction of energy sources such as coal and oil, there is an increasing emphasis on the reasons for renewable energy. Wind power generation is the cheapest and most promising renewable energy source, and it is a green energy source that does not pollute the environment. The general location of wind farms is relatively remote, with a harsh geographical environment. The staff live far away from the site, and each wind farm is far apart. There are also many wind turbines in each wind farm, so each wind farm needs to be equipped with a certain number of staff for daily inspection and maintenance, resulting in personnel waste; Wind power plants are usually located on the windward coast, shallow coastal areas, and flat or hilly areas in inland uninhabited areas. These areas are sparsely populated and have harsh environments, and are prone to neglecting their safety precautions and maintenance due to the rarity of human traffic. In response to this phenomenon, major enterprises have begun to shift their thinking and embarked on the path of remote monitoring and maintenance of wind turbines. Remote control and pitch monitoring of wind turbines will become important development trends in the industry.

Solution: The remote control system of the wind power generation system consists of two parts: an industrial gateway and an IoT cloud platform.

The industrial gateway collects the data of controller devices such as plc at the lower end, uploads the data to the EMCP cloud platform, and provides functions such as device networking and edge computing; The cloud platform is the operational platform for this solution, where relevant device data, report information, operating parameters, etc. are summarized and displayed, providing users with analysis and decision-making basis. At the same time, user management and control of devices are also carried out on the cloud platform.

The remote monitoring system for wind power generation consists of three parts: sensor devices such as wind meters, wind direction meters, temperature and humidity meters, voltage and current meters, gateway acquisition devices, and cloud platform/mobile monitoring centers. The gateway collection device is connected to the power generation sensor device, and the gateway transmits the real-time data collected to the monitoring center through wireless/wired networks. Since Internet transmission is not limited by distance, multiple terminal devices can be connected to a monitoring center at the same time, so a monitoring center can monitor multiple PLC and other control devices. The monitoring center is mainly responsible for processing the data sent by each terminal, and displaying and saving historical data in real-time on the computer. At the same time, the monitoring center can also provide real-time alarms for any hazardous data that may occur.

Real time monitoring device data

Real time monitoring of data from sensors such as wind meters, wind direction meters, temperature and humidity meters, voltage and current meters, oil pressure and liquid level sensors, and motor tachometers, supporting remote debugging and downloading of equipment PLCs, making message communication faster and more convenient. Can quickly set up the same monitoring screen as the scene. Monitor the status of the wind power plant remotely as if you were on-site. This can solve the problems of difficult equipment maintenance, difficult business trips, and delayed information acquisition.

2. Alarm remote monitoring

For the collected data, if any abnormalities occur, the device monitoring system will automatically perform an alarm function and send alarm information to the management personnel through various methods (message push, SMS, phone) in the first time.

3. Automation of operation and maintenance work order inspection

Users can quickly submit maintenance work orders through the app, and the operation and maintenance team designates personnel to carry out maintenance and repair, and forms records and archives on the platform. The operation and maintenance team can also develop inspection plans, assign personnel to inspect and maintain designated equipment, and form records for archiving, greatly improving operation and maintenance efficiency.

4. Realizing Green Energy Management

By utilizing cloud configuration editing for visual display and combining page scripts and 3D scene applications, comprehensive digital construction can be carried out to make wind farm monitoring more intuitive and control more precise, improve the overall management level and operation efficiency of wind farms, and promote the transformation and upgrading process of green and intelligent wind farms.

5. Refined operational management

It can achieve process management and operational management of the entire wind farm system, improving the management efficiency of the wind farm system. Real time understanding of the operation of wind farms through data panel information to achieve precise management. Using big data analysis and wind power model simulation technology, quantitatively analyze various operational indicators in the operation process, and use digital to drive the operation management and decision-making of wind turbines.

6. Transparency in monitoring and management

Realize remote monitoring and unmanned operation. Through remote intelligent control, balanced transportation and precise adjustment can be achieved in the central control center, and timely detection and repair of wind turbine losses can be achieved to ensure the safe operation and maintenance of the wind farm.

7. Future development of security monitoring

Due to the fact that most wind power plants are located in remote areas, monitoring must meet the requirements of unmanned, remote, high-definition, and networked. However, as some wind power plants are located in coastal recreational areas, the safety and confidentiality of wind power plants and transmission line security have become very important. Therefore, 3G architecture transmission has become one of the development needs of wind power plants in monitoring, real-time transmission of images and data. With the shortage of electric energy and the continuous development of wind power plants, the application projects and solutions for safety monitoring in wind power plants will also be continuously improved, moving towards an integrated system for safety monitoring in wind power plants, including high intelligence, automation, and integration of environmental and equipment monitoring systems, anti-theft systems, fire protection systems, and alarm systems.
