Measurement of Weather Parameters via Transmission Line Monitoring System for Load Forecasting

Climate has significant impact on generation, transmission and demand of electricity. There is need to manage weather and climate effects to avoid penalties due to incorrectly predicted demand. The effect of weather changes is seen through fluctuation of electricity demand. Electricity demand is influenced by temperature, wind speed, humidity, precipitation and cloud cover. This further effects practically demand for air conditioning, space heating, refrigeration and water pumping loads. This changes the peak demand and 24 hour demand. Transmission systems are found to be sensitive through thermal constraints and faults caused by extreme weather conditions. Demand levels are also weather sensitive. Thus all these pose serious challenges to electricity supply industry. It is also true that the forecasted load by load forecasters at load dispatch center, depend on the reliability of line that weather it is conveying that much of MW share to all related areas. Transmission system should be protected from weather effects. So proper means like some type of devices should be equipped over the tower which should sense the weather factors like temperature, humidity etc in prior. This paper presents the device named transmission line monitoring system for the measurement of weather parameters.
