  • Relevant parameters in wind farm production

    After the connection of a Wind Farm to the grid several parameters are used to analyze the smooth operation of the installation. The more relevant are: Capacity Factor [latex size=”1″]CF=\left( \frac{E(kWh)}{P(kW) T(h)}\right )[/latex] Is a parameter used frequently in power producing  plant. A high capacity factor means that the plant is working almost continuously (for…

  • Wind Energy in Jordan
