With the increasing amount of wind power generation connected to the power grid, the importance of measuring the wind turbines’ power characteristics and power quality characteristics is growing. By capturing this data, one can achieve improved utilization of the turbine by manipulating its control systems in accordance to power grid requirements for voltage/frequency fluctuations and fault con...

Smart grid puts forward higher requirements for power quality. Power quality evaluation can provide a decision-making basis improvement. Based on monitoring data, grey target method is proposed evaluation. The composed of standard and data to be evaluated. Combining with the characteristics each index, center whole system found. Then, evaluated mode are compared analyzed construct correlation d...

In the past few years, technical progress has determined traditional electric power system conversion to Smart Grids, and consequently empowered a worldwide renaissance in forgotten PQ field. Since installation of monitors is currently associated with high investments operational costs, it inappropriate install monitor on each grid busbar. Hence, operators must establish best cost–benefit scena...

Power quality monitoring has expanded from a means to investigate customer complaints to an integral part of power system performance assessments. Besides special purpose power quality monitors, power quality data are collected from many other monitoring devices on the system (intelligent relays, revenuemeters, digital fault recorders, etc.). The result is a tremendous volume of measurement dat...
