6 FAQs about [Insulation measurement of wind turbine generator]
How is partial discharge measured for operating turbine generator?
The online partial discharge measurements for operating turbine generator were carried out by the IRES equipment [ 14, 15, 16]. The test equipment detects and record voltage magnitude, phase angle and number of partial discharge pulses at each EMC. Then PD data viewed immediately by PDViwe and stored for a subsequent analysis.
What are the common faults of a wind turbine generator?
Common faults of wind turbine generator. Generator electrical faults are mainly stator eccentricity, rotor eccentricity, broken rotor bars, and looseness. The main manifestations of generator stator faults are overheating of stator windings, insulation damage, and grounding.
How many MW is a wind turbine?
TABLE 1. The technical route and main products of the world's main wind turbine manufacturers are above 3 MW. 2 Onshore 3. X platform with a power of 3.4 MW and rotor diameters of 132 m and 145 m, respectively; Onshore 4. X platform with a power of 5.0 MW and rotor diameters of 132 m and 145 m, respectively; Onshore 5.
What is a wind turbine generator failure analysis & fault diagnosis?
In this article, a comprehensive and up-to-date review of wind turbine generators failure analysis and fault diagnosis are presented. First, the electrical and mechanical failures of various WTG components, including stator, rotor, air gap, and bearings, are analyzed. Then, the fault characteristics and root causes of WTG are studied.
How to identify wind turbine faults?
Literature proposed a strategy containing wavelet transform, feature analysis, judgment, and back propagation neural network (BPNN) classification (WT-FA-JD-BP) to identify the wind turbine systems' faults. As shown in Figure 16. First, the original voltage signals under different faults are collected.
What is a stator winding in a turbine generator?
The stator winding of the turbine generator per phase consists of several parallel paths and each path of each phase consists of series connected bars. When the TG is under operating an electromagnetic field (EMF) is induced in each bar in slot part of the stator winding.
