“…By detecting the change of temperature signal, the misalignment of the shaft can be detected [66]. Researchers achieved non-intrusive thermal monitoring by signal injection without needing redundant thermocouples, which has a certain reference value for thermal protection of WTs [67]. The biggest challenge facing the temperature signal is that it is greatly influenced by the surrounding environment.…”

Wind power, as a renewable energy for coping with global climate change challenge, has achieved rapid development in recent years. The breakdown of wind turbines (WTs) not only leads to high repair expenses but also may threaten the stability of the whole power grid. How to reduce the operation and the maintenance (O&M) cost of wind farms is an obstacle to its further promotion and application. To provide reliable condition monitoring and fault diagnosis (CMFD) for WTs, this paper presents a comprehensive survey of the existing CMFD methods in the following three aspects: energy flow, information flow, and integrated O&M system. Energy flow mainly analyzes the characteristics of each component from the angle of energy conversion of WTs. Information flow is the carrier of fault and control information of WT. At the end of this paper, an integrated WT O&M system based on electrical signals is proposed.

“…However, the insulation of the temperature sensor is not cost-effective and temperature sensor reliability problems may occur. Motor internal temperature estimation methods can be classified into thermal model methods [7][8][9][10], and motor parameter estimation methods [11][12][13][14][15]. The lumped-parameter thermal network [7] is the most well-known thermal model method.…”

“…This approach has significant advantages over the thermal model method. The accuracy of the stator temperature estimation is not affected by the motor specifications, cooling method, or operating conditions [11,12], and the stator resistance can be estimated from the electrical equivalent model of the motor [13]. However, the stator resistance is significantly small and the performance of the temperature estimation is too sensitive to motor inductance variations [2].…”

Temperature Estimation of Stator Winding in Permanent Magnet Synchronous Motors Using d-Axis Current Injection

This paper presents a stator winding temperature detection method for permanent magnet synchronous motors (PMSMs) using a motor parameter estimation method. PMSM performance is highly dependent on the motor parameters. However, the motor parameters vary with temperature. It is difficult to measure motor parameters using a voltage equation without additional sensors. Herein, a stator winding temperature estimation method based on a d-axis current injection method is proposed. The proposed estimation method can be used to obtain stator temperatures and to achieve reliable operation. The validity of the proposed method is verified through simulations and experimental results.
