变频器在STATCOM风冷循环系统的应用
|
摘要
对传统STATCOM风冷循环系统进行改进,通过链节单元采集IGBT内部热敏电阻,计算出IGBT内部温度并通过光纤上传到控制器,控制器根据温度最大值计算出当前风道所需的风量,从而控制变频器工作在合适频率。该冷却系统直接采集IGBT内部热敏电阻值,确保IGBT工作在最佳温度状态,变频器的引入避免了风机的频繁启停,提高了风机使用寿命,降低了装置噪音。
An improvement to the traditional STATCOM air cooling circulation system is proposed in this paper.The temperature data from IGBT internal thermistor was collected through the link unit.The internal temperature of IGBT was calculated and uploaded to the controller through the optical fiber.The controller calculated the air volume required by the relevant air duct according to the maximum temperature and control the frequency converter working at the appropriate frequency accordingly.The cooling system will be reacting directly according to the IGBT internal temperature which ensures that IGBTs work in the best temperature state.By adopting frequency converters,frequent start and stop of the fan can be avoided which improves the lifespan of the fan and reduces the noise of the device.
