Permanent-Magnet Synchronous Generator it can provide highly reliable power generation with small in size, no copper losses in the rotor circuit, no need for external excitation. We designed and simulated the PMSG with 12 slots and 8 poles with an alternating polarity magnet configuration: NN-SS-NN-SS-NN-SS-NN-SS-NN-SS-NN magnetic flux per pole in the outer stator and the inner stator has been assumed to be constant, following sizes and materials described in this paper. The generator's number of poles is determined by stacking several sections of the magnet side by side and grouping opposite poles in a continuous pattern. the initial design of the PMSG 12 slots and 8 poles outer-runner compare to see how the halbach array configuration changes the output parameter, it will be included. Proportional to the load size and speed The larger the magnetic flux generated by the movement of the magnetic field, the higher the rpm, and the heavier the coil magnetic flux obtained, the higher the induced voltage. This research use five speed variations varying from 1000 to 5000 rpm and load variation from 5 ohm, 15 ohm, 30 ohm, 60 ohm, and 100 ohm. With the effect that the flux distribution is voltage generated at a 5 ohm load only increases at 1000 rpm, while the increase in torque produces an increase in the amount of input power at 30 ohm, which is equal to both the speed and the amount of torque, where the input power increases at all speeds at a load of 30 ohm. This also arises when the output power generated at a load of 30 ohm increases by a high efficiency of over 86%.

Renewable Energy System

One of the most important ways to reduce fossil fuel consumption and consequently reduce greenhouse gases and environmental pollution is the use of renewable energies such as water, sun, wind, etc. One of the most efficient ways to take advantages of the shallow flowing waters such as rivers and fountains in electrical power generation is the use of hydrodynamic screw in the direction of water flow. The design of the generator for this application results in environmental dangers decrease. On the other hand, it provides some part of electrical energy required for human beings. Generators in hydrodynamic renewable energy system ought to have features such as high efficiency, power density and reliability as well as low volume. Among various generators, the permanent magnet synchronous generator (PMSG) meets these requirements very well. In this paper, first, analytical calculations and the design process of PMSG were explained. Then, the ant colony optimization (ACO) was used for the optimization of design quantities. PMSG design optimization increased in efficiency and decreased in volume. By improving these two parameters in the designed PMSG, it gets very suitable to be used in hydrodynamic renewable energy system. Finally, the results of the optimized design of PMSG were validated through simulation of it in Maxwell software and applying finite element analysis (FEA). Also the final results have been compared to similar experimental researches results.

In this paper, an improved Maximum Power Point Tracking (MPPT) algorithm for a tidal power generation system using a Support Vector Regression (SVR) is proposed. To perform this MPPT, a tidal current speed sensor is needed to track the maximum power. The use of these sensors has a lack of reliability, requires maintenance, and has a disadvantage in terms of price. Therefore, there is a need for a sensorless MPPT control algorithm that does not require information on tidal current speed and rotation speed that improves these shortcomings. Sensorless MPPT control methods, such as SVR, enables the maximum power to be output by comparing the relationship between the output power and the rotational speed of the generator. The performance of the SVR is influenced by the selection of its parameters which is optimized during the offline training stage. SVR has a strength and better response than the neural network since it ensures the global minimum and avoids being stuck at local minima. This paper proposes a high-efficiency grid-connected tidal current generation system with a permanent magnet synchronous generator back-to-back converter. The proposed algorithm is verified experimentally and the results confirm the excellent control characteristics of the proposed algorithm.

This paper presents a high efficiency drive strategy for micro-turbine generator (MTG) in which permanent magnet synchronous generator (PMSG) is used. PMSG operates at maximum efficiency point by optimizing the phase of armature current of PMSG; i.e., an optimum d-axis current in the rotor reference frame is analytically derived from mathematical model of PMSG taking iron loss into account. In addition, in order to use turbine output power effectively, compressor input power is minimized by optimizing revolving speed of PMSG. Simulation results confirm validity of the proposed method.
