Analysis of the development of the domestic sensor market Li Jianlin, associate researcher of the New Energy Group of the Institute of Electrical Engineering of the Chinese Academy of Sciences, said: “The wind power industry will measure the application of high voltage, high current sensors, vibration sensors, temperature, humidity, wind measurement, and pressure sensors. It is advancing." Among them, since the current sensor is an indispensable component of the converter in the wind turbine, its application in the wind power industry is particularly important. In some inverters, small and PCB mounted current sensors are used in a wide range of applications. These sensors are part of the converter's closed-loop control and ensure that the inverter reacts quickly.
When the inverter is used in conjunction with the smart power control of the generator, it can be ensured that the continuous power of the grid is provided over a wide range of wind speeds after the wind turbine is started until the turbine is shut down at the upper wind speed. In order to optimally position the driver, the sensors in each converter continuously measure the current, and the quality and reaction time of the circuit controller are ultimately determined by the design and performance of the current sensor. This is why closed-loop current sensors with low current ratings are widely used in the wind power industry. In addition to excellent linearity and accuracy, closed-loop current sensors also have high bandwidth and fast response time.
Market Development Analysis The domestic sensor market is yet to be developed, especially the large current sensor technology, which lags far behind the international level. However, with the development of economy, the development needs of new energy industries such as rail transportation or wind power will drive the development of domestic sensor technology. More and more sensor manufacturers will turn their attention to rail transportation, new energy and other industries.
