Industrial Switches In The Field of Wind Power Generation

Recently, Mr. Wu Lin, Marketing Director of Shenzhen Houshi Network Technology Co., Ltd., expressed his views on the application of Industrial Switches in wind power. The full text is as follows:

Mr. Wu Lin said that at present, my country has become the largest and fastest-growing market for wind power generation in the world.According to the statistics of the Global Wind Energy Council, the cumulative installed capacity of wind power in the world increased from 23,900MW as of December 31, 2001 to 486,749MW as of December 31, 2021, with a compound annual growth rate of 22.25%, while the compound annual growth rate of my country's cumulative installed wind power capacity was 49.53% in the same period, ranking first in the world in growth rate; in 2021, my country's newly installed wind power capacity is 23,328MW (provisional data), accounting for the year's new global installed capacity 42.7% of the capacity, ranking first in the world.

With the large-scale construction of wind farms, wind farm information management systems and wind turbine remote monitoring systems have also been widely used.These systems have harsh application environments and require managed wide-temperature industrial switches for network support. Therefore, the Chinese wind power market has higher and higher requirements for industrial switches.

Requirements for industrial switches in the field of wind power generation

The fundamental task of the communication network is to solve the real-time information exchange of the wind farm system, and the network is an indispensable functional carrier, so building a reliable, real-time and efficient network system is one of the keys to communication.The requirements for communication equipment in the wind farm system are mainly reflected in the following aspects:

1. Reliability

Due to the continuity and importance of electricity production, the reliability of the communication network is the first priority, and it should be avoided that the failure of one device causes the communication to be interrupted.Especially the application of multimedia technology of digital and image information, we will rely more on the communication network, therefore, a reliable communication network is the primary condition.

2. Security

To ensure the security of remote monitoring data, industrial switches need to have network management and security settings.

3. Real-time

Because measurement and control data, protection signals, remote control commands, etc. all require real-time transmission, although the data flow in the communication network is not large during normal operation, a large amount of data needs to be transmitted in the event of a failure, and information is required to be quickly transmitted on the communication network.

4. Environmental adaptability

The application environment of the wind farm is harsh, the wind and sand are severe all the year round, and the temperature difference between day and night, winter and summer is large, which requires the switch to have a wide operating temperature range and a higher protection level.There is a very strong electromagnetic interference in the wind farm, which requires the switch to have a strong anti-electromagnetic interference capability.

Analysis of the application scheme of industrial switches in wind power generation systems

By analyzing the actual needs of wind power generation, the industrial switch networking solution provided by Houshi Network mainly considers the following aspects:

1. Using a unified and open protocol, it can seamlessly connect network equipment from different manufacturers, with high cost performance.

2. The wind farm is built in an open area and is easily disturbed by strong lightning strikes. The local climate and environment are relatively harsh, and the mechanical vibration and electromagnetic radiation of the wind power equipment itself are relatively large. Therefore, the wind farm center monitoring system and the wind turbine local control system The reliability of communication between them is very important, which will directly affect the reliable operation of the monitoring system of the entire wind farm.

3. Due to the large scale of the network, the networking scheme adopts a clear multi-layer structure, which simplifies the maintenance and management of the network from the most fundamental network structure design, realizes the rapid separation of fault points, and ensures the stable operation of the system.

4. The networking solution must have certain troubleshooting and fast self-healing functions, which can diagnose and quickly eliminate equipment failures and link failures, and alarm in real time.

5. Taking into account the real-time requirements of the industrial site, the ring network design concept is adopted to avoid the impact of a single link failure on the network.

6. In order to ensure the security of remote monitoring data, the switch needs to have comprehensive network security settings.

The topology diagram of the wind power system network scheme of the industrial switch of Houshi Networks

In this solution, an IS3000 series industrial switch is placed at each fan, the industrial switch at the fan and the IS3000 series industrial Ethernet switch at the control center are interconnected through optical fibers to form a ring network, and then the IS3000 series industrial switch in the control center is connected through RJ45 The Ethernet interfaces are respectively connected to two core IS6000 series industrial switches, and the server and host in the control center use dual network cards to connect to the two core switches respectively.

The IS3000 series industrial switches in the ring network enable the ERPS protocol function, which realizes the redundancy of the network link and ensures the worry-free switching of the network. The network self-healing time is less than or equal to 50ms.Enable the VLAN virtual local area network function of the switch in the networking to isolate different services in the wind power system to prevent the broadcast storm of the service from affecting other services, and enable the broadcast storm suppression function on each service access port of the switch to effectively transmit data. , the role of invalid data suppression, improve the security of network data transmission.At the same time, the QOS service quality function is used to allocate bandwidth to the access ports of the switch according to different service levels, so as to improve the efficiency of network data transmission.

The network topology is shown in the following figure:
