THE ONLINE COMPREHENSIVE SYSTEM FOR MONITORING, CONTROLLING, METERING AND PROTECTION OF DOMESTIC/DISTRIBUTED GENERATION

摘要

The performance of wind power generation where it is aimed to obtain efficient and economic energy production, when connected to power network is discussed. As the wind speed is not always constant, the fluctuations in it reflect the output power, but the voltage and frequency should be kept as stable as possible. This is possible by using PLL which allows the system to be in synchronization. The optimized power at the required voltage and frequency using an inverter is fed to the load and as the demand is satisfied it delivers the excess power to the grid. The parameters like voltage, delta, power factor comes across this are discussed briefly. Here an algorithm is developed in such a way that it can control the entire system, so that the power can be used in an efficient and economic manner. The circuit breakers are automatically operated according to the change in the availability of power from DG like wind speed by the control circuit. This improves the performance of wind power generation when connected to the utility grid. The process of monitoring, metering, controlling and protection is discussed in a well manner and the cases of paying, saving, earning are explained by using figures. For the same a model is developed and simulated in MATLAB and the results are analyzed. Proposed invention is described in detail with the help of Figure 1 of sheet 1 shows the cases of paying, saving and earning and Figure 2 of sheet 2 shows Single line diagram of the proposed wind energy system connected to utility grid.
