Study on power grid wind hazard precaution system based on PLS-MOS

The severe wind is one of the greatest threatening natural disasters to power grid operation. According to the difficulties encountered in evaluation and forecasting of severe wind intensity, a severe wind statistical diagnosis model is proposed in this paper by using Partial least-squares and Model Output Statistics (PLS-MOS) methods. This model can accurately predict severe wind speed in the power grid region through interpolation smoothing to the forecast result of each weather site. Furthermore, combining with the wind-resistant design parameters of transmission tower, a power grid wind hazard precaution system based on electric power GIS (EPGIS) platform is supplied in order to remind the relevant operator for their decision-making and emergency treatment through real-time SMS and GIS location display. This system can further perfect the hazard prediction and precaution system, and improve the forecast ability of the severe wind hazard. It is of important practical significance and application value for power grid disaster prevention and reduction.
