In this paper, a multi-objective optimisation procedure based on the non-sorted genetic algorithm-II (NSGA-II) for the design of a buried PM wind generators with variable-flux is presented. A comparative analysis is carried out for optimised 13 kW, 100 kW and 1 MW buried-PM variable-flux synchronous generators (VFSG) with PMs buried deep in the rotor cores and additional rotor field coils. A design...
Grid compliance is a crucial feature for modern wind turbine systems in power generation. The generator is one of the key components in a WTS. However, in order to predict the response of a directly grid connected wind generator to grid code requirements, an optimisation-based design over a large design space is needed. In this research, an analytical design model is developed for a grid compliant...
Grid-compliant wind-turbine systems require compensation of reactive power into the grid to maintain voltages and increase power system stability under variable load levels. To provide a solution a conventional PM synchronous generator of a slip synchronous wind generator system is upgraded to a hybrid-PM synchronous generator (hybrid-PMSG) by introducing slots in the rotor that are wound with field...
This paper focuses on studying the operating control of direct-drive grid-connected wind-power generation system of variable speed PMSWG. After wind turbine simulation is analyzed first, the closed-loop current control method of DC motor based on BUCK speed regulating circuit is put forward. Non-controllable rectifier and grid-connected PWM inverter is adopted as the AC grid-connected circuit of PMSWG...
Buerjin power grid of Xinjiang province in China is an alone hydraulic-wind power mutual compensation system, which is composed of two hydraulic generators with capacity of 2000 KW and one with 2500 KW and seven wind generators with capacity of 150 KW, the wind power capacity account for almost 13.0 percent of total power system capacity. In order to study the optimal capacity scheme of wind power...
This work presents firstly a description of simulation models for use in PowerFactoryTM and ATP programs for transient stability studies of power systems with wind turbines. Based on these models, simulation modules for both platforms were developed, the objective is to allow an evaluation comparing a digital simulator of transients with free distribution, ATP, with a reference program internationally...
