Example Embodiment

[0025] Step 1 Selection of SCADA temperature parameters

[0026] The method for evaluating the safety status of wind turbines based on temperature parameter analysis requires that the selected temperature parameters should be able to reflect the operating state of the equipment and be sensitive to the abnormal operation of the equipment; The bearing temperature on the driving side of the generator, the bearing temperature on the non-driving side of the generator and the winding temperature of the generator, the pitch system selects the pitch motor temperature (such as figure 1 shown).

[0027] Step 2: Analyze the operating parameters associated with the selected SCADA temperature parameters

[0028] The operating conditions of the wind turbine are different, and the temperature parameters of each subsystem are also different, and the working conditions correspond to the temperature; the ambient temperature can affect the basic temperature of the equipment; heat dissipation ca...

Abstract

The invention discloses an SCADA (supervisory control and data acquisition) temperature parameter based wind turbine set security evaluation method and belongs to the technical field of equipment security evaluation. The wind turbine set security evaluation method includes: firstly, deciding on an SCADA temperature parameter; then analyzing temperature parameters related to system faults of a wind turbine set, structuring relatedness between operating conditions of the environment temperature as well as wind speed and the SCADA temperature parameter, determining a standard for division of wind turbine set operating conditions, and establishing a standard Gaussian model serving as a reference model for evaluation of the wind turbine set operating conditions; calculating degree of deviation between a curve and the standard model through comparing the standard model with the Gaussian model, and measuring the operating condition of the wind turbine set. By the application of the wind turbine set security evaluation method, monitoring level upon the wind turbine set can be improved, utilization rate of the wind turbine set can be increased, and operation cost can be effectively lowered; a reliable and effective wind turbine set security evaluation mechanism is established, so that deterioration of hidden trouble of the wind turbine set towards faults and accidents is avoided, and an operation circumstance which is secure, stable and efficient is formed for the wind turbine set.

Description
