“…Wind turbine performance is not merely dependent on the turbine hardware and the control system plays an essential role. The main purpose of the control system is to absorb the maximum possible power and ensure the level of power at a constant level despite load variations and other factors (Kamarzarrin 2015;Kayikci 2007;Yi et al 2018). Figure 6 shows an overall view of the wind turbine control system and the interactions between them.…”

Today, the generated electrical energy using renewable energy is rapidly growing all over the world. The speed and direction of the wind are fundamental parameters affecting on power production of wind turbine that is constantly changing. One of the methods for controlling wind turbine power is changing the angle of the blades. In this paper, an adaptive control method has been used to control the wind turbine pitch angle. The proposed method is based on sliding mode control, whose coefficients have been calculated using the particle swarm optimization-support vector machine method. In order to evaluate the effectiveness of the proposed method, it has been compared with the Model Reference Adaptive Controller (MRAC) in the operating under disturbance. The results show that the proposed controller has a better performance than that of the MRAC in the presence of disturbance. Simulations show that the produced power at different wind velocities has reached its optimum value faster.

“…The angle changes are generally between zero and 35°. However, in order to stop the turbine in severe winds, this angle is placed in 90°to 95° ( Jiawei et al 2013;Moazen et al 2016;Yi et al 2018). Figure 7 shows the block diagram of the pitch model of the wind turbine.…”

“…Existing works on the effects of wind on HVDC transmission lines have been expanded to include the time-varying characteristics of wind and the factors that influence wind speed. Based on the time series model and the Kalman filter method, short-term wind speed was used to predict the ion flow [5]. The simulation was done by the FEM and time-domain FVM method.…”

Ion flow field is an important aspect of high voltage direct current (HVDC) transmission lines. In this paper, we apply the upwind finite volume method for solving the ion flow field of three HVDC configurations to clarify the effect of the wind and the role of shielding conductors. For the monopolar configuration installation, the ground current distribution with underbuilt shield wires was studied numerically and experimentally. For the ±250 kV bipolar configuration, the calculated peak electric field and current density are verified with the values in a reference. The ±500 kV bipolar configuration is used to investigate the change in electric field and ion current within the same corridors of the existing HVAC lines. We analyze the ion flow field with and without the dedicated metallic return conductor (DMRC). In the absence of wind, the maximum of the electric field is lower than that of the HVAC lines and the current density is very low on the ground. In the presence of wind, the electric field and the current distribution become unsymmetrical on the ground level. The peak current density increases significantly on the downwind side. The HVDC line without DMRC has the electric field peak higher than that of the HVAC lines. With the higher wind shear coefficient, the peak of the electric field and the current density increases on the downwind side. Overall investigations summarize that DMRC can effectively reduce the peak of the electric field to be lower than that of the existing 500 kV HVAC lines under all wind conditions.

“…However, power supply of these electrical sensor components in the field environment is difficult. In addition, the sensors are suffering strong electromagnetic interferences from the high‐voltage cable itself and damages from thunderstorms and other bad weather [19]. Thus maintenance of large‐scale sensor array is not easy in the long‐distance monitoring of the transmission lines.…”
