Abstract: With the construction of intelligent power plant, the unit condition monitoring is getting more important. By adopting the light scattering mechanism, the particle size analyzer is developed independently in the laboratory and gets calibrated and verified. After it is applied in the governor oil system of Hongjiang Hydropower Plant Unit 2, a potential of oil pollution is discovered, indicating that the monitoring data can reflect the operating conditions of the unit. Through comparison, it is concluded that the analyzer online monitoring results are consistent with those of the particle counters of HACH 8011+ and PAMAS SBSS, which proves that the light scattering method is highly accurate and suitable for online monitoring the turbine oil particle sizes and can provide a support for the change of condition maintenance from planned maintenance. The analyzer developed also has the characteristics of low cost and good stabilities.
