“…Because the offshore AC grid is formed by the distributed wind turbines [25][26][27][28][29][30], the maximum power point tracking (MPPT) is difficult to achieve. Moreover, a real wind farm usually contains tens or hundreds of wind turbines, and the coordinate control of such a number of turbines is also challenging.…”

The exploitation of offshore wind power has increased rapidly in recent years. To gain more wind power energy, offshore wind farms move farther from onshore. A comparison between HVAC and HVDC in terms of reliability, cost and transmission capability shows that HVDC is more suitable for long-distance, high-capacity bulk power transmission. However, the HVDC transmission for offshore wind power also faces great challenges because the offshore applications bring critical demands for low volume and low weight for the converters at the offshore side. On the other hand, the new topologies and conversion techniques of power electronic converters expedite many new DC transmission architectures for offshore wind power. Different HVDC architectures by using centralised voltage source converter (VSC), diode rectifier (DR), series-connected wind turbine converters and all-DC wind farm based on DC transformers are reviewed and compared. The advantages, challenges and development and application prospects for various DC transmission solutions are discussed.

“…Model and control scheme of wind turbines controlled by the onshore VSC. An offshore AC grid is formed with distributed wind turbine converters[25][26][27][28][29][30].For the turbine converter, the grid side inverter is modelled as inFigure 9(a)[25]. The corresponding control scheme is demonstrated inFigure 9(b) [25].…”

“…Three-phase PWM VSR systems have been incrementally applied in the field of renewable energy systems, uninterruptible power supplies (UPSs), motor drivers, and so forth and have become an indispensable energy conversion device (Yang et al, 2016;Li and Yang, 2017;Bueno and Pomilio, 2018;Zhang et al, 2021). However, most of the renewable energy equipment is built in the mountains or remote areas away from the coast as the probability of sensor faults is very high under harsh climates or conditions (Bidadfar et al, 2021). Once the fault occurs in the key sensors related to the control system, it may cause the whole system to crash or run inefficiently (Peng et al, 2018).…”

A Random Forest and Current Fault Texture Feature–Based Method for Current Sensor Fault Diagnosis in Three-Phase PWM VSR

Three-phase PWM voltage-source rectifier (VSR) systems have been widely used in various energy conversion systems, where current sensors are the key component for state monitoring and system control. The current sensor faults may bring hidden danger or damage to the whole system; therefore, this paper proposed a random forest (RF) and current fault texture feature–based method for current sensor fault diagnosis in three-phase PWM VSR systems. First, the three-phase alternating currents (ACs) of the three-phase PWM VSR are collected to extract the current fault texture features, and no additional hardware sensors are needed to avoid causing additional unstable factors. Then, the current fault texture features are adopted to train the random forest current sensor fault detection and diagnosis (CSFDD) classifier, which is a data-driven CSFDD classifier. Finally, the effectiveness of the proposed method is verified by simulation experiments. The result shows that the current sensor faults can be detected and located successfully and that it can effectively provide fault locations for maintenance personnel to keep the stable operation of the whole system.

“…With the focus on low wind speed speeds, an optimization procedure for generator to rotor ratio based on energy cost is given in [12]. A diode rectifier based system is suggested by [13] as the promising low cost solution for exporting wind power from remote areas. The cost analysis obtained using steady state and dynamic wind turbine models of actual small wind turbines realized in the urban areas of UK are given in [14].…”

This paper is concerned with the design, implementation and monitoring of wind energy conversion system for domestic applications. It is speculated that at most of the places in India, windmills will not be viable due to low wind speed. Hence, a generator with sufficient torque control and having the tendency to produce energy even at very low speed is required. The proposed work has been implemented to generate electricity at low wind speed used for household applications. The main objective intended is to manufacture a cost effective wind turbine and produce effective power when compared to the windmill available in the domestic market. The overall design consists of 3 blades using NACA 63215 profile which is made up of fiber glass material. The permanent magnet synchronous generator with the permanent magnet of alnico type is used to produce the power of 250 W. The power charged in the lead acid battery of rating 24 V; 150 Ah is utilized by the load using power electronic converters. The micro wind turbine operated at wind speed as low as 4.8 m/s and the output power thus obtained was 250 W. The measuring system employs anemometer to measure wind speed, potentiometer to measure wind direction, LM35 sensor to measure generator temperature and hall sensor to measure the generator voltage and load current. All the parameters are monitored continuously to evaluate the performance of the turbine. Since the operating wind speed and production cost is low, the proposed system will serve the basic necessities in meeting the requirements of household appliances. A detailed comparative study is carried out to show the effectiveness of the proposed design.
