Power Generation System

In this literature, a new automated control strategy has been developed to manage the power supply from the wind power generation system to the load. The main objective of this research work is to develop a fuzzy logic–based pitch angle control and to develop a static transfer switch to make power balance between the wind power generation system and the loads. The power management control system is a progression of logic expressions, designed based on generating power and load power requirement. The outcome of this work targets at an improved power production, active and reactive power compensation and ensures system load constraints. To validate the proposed control strategy, a detailed simulation study is carried out on a 9-MW wind farm simulation simulated in MATLAB/Simulink environment.

The Impact

The impact of grid-connected photovoltaic power on power quality and reliability of power supply has gained more attention, with the continuous improvement of its generation capacity. This paper describes the power conditioning system of grid-connected photovoltaic power plants based on super-capacitor energy storage, which acts as the energy storage element to stabilize fluctuations in output active power of photovoltaic power generation system. Based on the configuration and principle of the power control system, a power and current double closed loop feedback hysteresis current control strategy is proposed in details, which controls the super capacitor energy storage system to absorb and complement the active power output fluctuations of the photovoltaic power generation system. The effectiveness and good operating performance of the device and control strategy are validated by simulation with PSCAD/ EMTDC.

Save Energy

The technology of Ship Shaft Power Generation System (SSPGS) is an effective way to save energy, Compared to the traditional SSPGS, the shaft power generation systems based on BDFG has the advantages of smaller capacity of the inverter, lower capital operational costs and higher reliability. In order to utilize rationally the resources, the paper analyses the ship operating mode, and presents the control strategy when the system working at grid-connected mode. The proposed vector control method is developed on the power winding (PW) stator flux frame and can be used to control both the active and reactive power on the grid-connected mode. The generator model and the control system are developed in Matlab/Simulink. The results show that the control strategy has good dynamic performance when the ship speed and power are change.
