“…HE last decade has witnessed an increasing interest of multiphase drives based on Permanent Magnet Synchronous Motor (PMSM) for aircraft [1], automotive [2]- [3] and off-shore renewable energy generation [4]- [5] because of their fault-tolerance and high power density. These systems have benefited from the huge development of electronic components for their control and supply [6]- [7].…”

A novel centroid-based diagnostic method of the power switches in five-leg Voltage Source Inverter (VSI) is proposed in this paper. Using a vectorial multi-machine description, a five-phase drive presenting an opened switch or an opened phase faults has typical operating characteristics in comparison to classical three-phase drives. Based on such characteristics, this work aims to provide a simple and robust diagnostic process for switches fault regardless of the shape of the back-EMFs (harmonic components) and the transient states due to the load variation. Original theoretical developments are presented. Experimental results are shown to validate the proposed strategy.

“…The symmetrical multiphase machines are usually those with odd phase numbers, like five-phase [4,9,19], seven-phase [20], and nine-phase [21] machines. And most of the machines with even phase numbers are in asymmetrical structures [5,[14][15][16], which have less torque pulsations than those in symmetrical structures [22].…”

The current imbalance between stator phase windings could shorten the motor life and affect the drive performance, whereas in case of multiphase drive applications, there is not a general current balance control strategy that can apply to symmetrical inverters with any phase number m. Based on the generalized Symmetrical Component Theory, this letter analyzed the values of relative symmetrical components of multiphase systems in balanced and unbalanced cases. Then developed from the conventional Rotor-flux Oriented Control (RFOC), the current-balance RFOC is proposed to compensate the current imbalance for symmetrical m-phase inverters. Finally, experiment results from the five-phase and nine-phase drive systems confirm the validity of the control strategy in eliminating current imbalance.

“…By exchanging information between the wind turbines, the distributed control strategy is formulated on the basis of the information obtained by each unit from its neighbouring units, thereby effectively realizing the control of the entire distributed network. Therefore, distributed control has been considered as a promising technique to be applied in offshore wind farms [10,11]. Furthermore, the consensus problem is the basis of the distributed control of multi-agent systems [12,13].…”

Distributed Complementary Control Research of Wind Turbines in Two Offshore Wind Farms

Abstract:In order to stabilize the fluctuation of wind power and maintain a stable power output, a complementary control idea is proposed. This idea aims to make the output power from two wind farms complement each other. This study proposes a distributed control strategy to solve the complementary control problem of wind turbines in two offshore wind farms on the basis of the Hamiltonian energy theory. The proposed control strategy not only ensures synchronization for wind turbines in the same farm but also keeps the combined output power of the two wind farms stable. First, through the Hamiltonian realization, the single-machine model of a wind turbine is transformed into a port-controlled Hamiltonian system with dissipation (PCHD). Subsequently, the Hamiltonian energy control law is developed on the basis of the energy-shaping method to adjust the Hamiltonian energy function. The complementary control of the two wind farms is designed to synchronize the wind turbines within an individual wind farm and keep the combined output of the two wind farms stable. Furthermore, the complementary control strategy is modified to address the communication delay between the two wind farms by incorporating time delay into the control problem. Finally, the effectiveness of the distributed complementary control has been verified via simulations.
