Complete renewable clean energy solutions

Nowdays we have gradually moved from traditional coal and other non-renewable fuels to renewable energy, and renewable energy applications are expected in the coming decades, especially wind and solar power generation has been identified as a viable energy alternative. At present, H&T products have been used in renewable energy projects around the world, such as wind power and solar systems.

Wind power

It is very difficult for wind power to establish a stable communication environment between wind power columns because of the large coverage of wind field and the need for long-distance data communication. In addition, because the electromagnetic interference is easy to occur in the wind turbine, the anti-interference of the product is also an aspect that needs to be evaluated, which can prevent the unstable transmission from causing the data loss. Based on these conditions, in the harsh wind environment, the remote monitoring system must adopt rugged network communication equipment.

Top of Wind column

The whole wind turbine  is divided into two parts: the top of the wind column and the bottom of the wind column. At the top, it contains a generator and all kinds of serial port equipment, such as water-cooled equipment, high-voltage transformer, ultrasonic velocimeter, gearbox, blade shaft, steering device and communication equipment. All of these devices are controlled through a PLC and then communicate with the ground host. In the process of integrating these devices into Ethernet, our customers put forward the requirement of connecting serial port devices to Ethernet, and asked the system to run stably. The serial port of H&T can realize serial port switching port. The switch HT3208I, at the bottom of the fan is connected to the HT3208I and other HT3208I through the optical port from the top engine room switch HT3208I, and the central equipment HT3224I, is connected to the control center. Industrial grade design, suitable for substation environment wind turbine environment is very bad, including extreme temperature, dust and strong wind interference. Our industrial Ethernet switch and serial port network server are fan-free, providing high MTBF, wide temperature working range, redundant power supply and rugged shell, so that system Integrator can build a reliable communication network.
