Abstract:

In the turbine supervisory instruments (TSI) of Anhui Huadian Wuhu Power Generation Company Limited, there are problems such as excessive temperature of DC power supply module and poor contact with the extension plug of vibration sensor. Through analysis, replacement with a more stable power supply module, optimization of the sensor connector and dispersing the arrangement of vibration measuring points are proposed, which improves the reliability of measurement and protects of the TSI system.
