Realization of remote management of wind farm based on remote monitoring system

China has vast land and wind resources. With huge investment and policy support, it has become the world's largest wind power producer, with installed capacity second only to thermal power and hydropower. However, due to the lack of desert or sparsely populated wind farms and poor external communication conditions, how to establish a remote monitoring system to strengthen wind farm management and improve efficiency has become a major challenge for wind power to continue to move forward.

The users of this case have dozens of wind farms in China. Although the wind farm has established perfect on-site monitoring through the optical fiber network, the external information is insufficient, and a comprehensive and integrated remote monitoring system has not been established with the headquarters of the wind power company. Headquarters is unable to understand and establish predictive data analysis in real time for the operation of wind farm equipment. It is often too long and time-consuming in equipment maintenance.

Through the introduction of Advantech Edge Intelligence Server (EIS, Edge Intelligent Server) and Advantech's WISE-PaaS/EdgeSense edge intelligence and wireless sensing integration software services, the wind power company successfully established a headquarters-to-local monitoring system, connecting all devices in series, and through Upload data over 4G wireless networks. EIS servers built in various wind farms have powerful data acquisition, storage and communication capabilities. They can build small databases, support breakpoints when communication is interrupted, and temporarily store data in wind farms with no communication signals. Features. In addition, WISE-PaaS/EdgeSense's powerful device connectivity capability not only allows the integration of existing wind farm internal monitoring systems, but also allows customers to easily connect more devices and add monitoring items through the use of external sensors, making the system extremely incomparable. Expand capacity, save time and money investment.

system requirement

The customer hopes to establish a remote monitoring network between the wind farm and the headquarters to monitor the working conditions of the wind farm equipment and the power generation situation, suspend the wind turbine operation when the wind is small; and statistically analyze the power generation rate of each wind farm and each wind turbine. , utilization rate, acquisition time and price, cost-effectiveness, operation with mobile equipment, and increase revenue.

In addition, customers want to add vibration detection projects. Each fan needs to build more than 10 vibration sensors, connect to the EIS, and analyze the data together with other data to detect whether the fan is running normally and perform predictive equipment maintenance.

Advantech Solutions

The system integrator responsible for the case set up an Advantech EIS edge smart server in each wind farm to establish a small database in the field and communicate externally through the 4G network. Both the headquarters monitoring center host and the local EIS servers installed Advantech's WISE-PaaS/EdgeSense edge intelligence and wireless sensing integrated software services, and successfully established a comprehensive central to local monitoring platform. EIS has the functions of data storage and breakpoint retransmission. When the communication signal is bad, it can continue to upload after the communication is restored, and preserve the correct and complete upload data.

In the new vibration detection part, the vibration sensor is built in the external connection mode, and the existing power, motor, temperature, voltage and other test data are gathered to the EIS server, and the cloud is uploaded for big data analysis and predictive maintenance of the equipment. model. Advantech's EIS is equipped with WISE-PaaS/EdgeSense with powerful (device) horizontal connection and (cloud) vertical connection capability, which can quickly integrate old and new equipment to remote intelligent monitoring platform, with unparalleled flexibility.

Customer benefit

1. Successfully set up a headquarters monitoring platform for customers, and collect and analyze data in the concept of “war room” as a reference for operational decision-making.

2. Solve the problem of professional manpower shortage in remote areas, master the operation of equipment through remote monitoring, and carry out predictive maintenance, saving manpower and material resources and preventing no early warning.

3. Quickly integrate existing equipment and new equipment, customers can flexibly increase monitoring projects according to their needs, and complete system expansion in the shortest time in the most economical way.
