What's the relationship between weather and electricity?

People are always inseparable from electricity in their production and life. With the improvement of people's living standards and the continuous improvement of modernization of all walks of life, the demand for electric energy is increasing, and the role of electric energy also shows great power, which is recognized by more and more people. "However, there is a very close relationship between meteorology and power supply. I'm afraid this has not been recognized by people. The first is that the demand for electric energy is related to the weather. It is hot in summer, and people are used to turning on air conditioners or electric fans to improve indoor microclimate and achieve the purpose of heatstroke prevention and cooling, thus increasing electricity consumption; When the weather is cold in winter, use electrical appliances for heating, such as air conditioners, electric heaters, electric blankets, electric heaters, etc. The power consumption is greatly increased: when a solid and towering cumulonimbus cloud is empty or a sandstorm comes, the power consumption for lighting will suddenly increase and the load will increase. These are all weather reasons. Therefore, according to the weather forecast information, it is an essential link to make a power supply plan and ensure power dispatching.

Secondly, the close relationship between power supply lines and weather. We all know that when there is a strong thunderstorm in summer, it will cause tripping or burn out the transformer; When typhoon or strong convective weather produces strong wind above 10, it is easy to scrape off power lines and blow down telephone poles, resulting in line failure or cross short circuit of Class II and III lines; When strong cold air invades in winter in the north, snow is easy to appear, which can make the ice thickness of power lines reach more than 2.5 cm, increase the gravity load of power lines, lead to the disconnection and pole reversal of high-voltage lines, and then cause partial or total power failure and abnormal power supply.

Third, the relationship between transformer maintenance and weather. Transformer, oil switch and cable head must be overhauled in sunny and dry weather. It can't be overhauled in rainy days, and it can't be overhauled when the air relative humidity is above 75%, otherwise the damaged transformer and cable head are easy to explode, so the determination of overhaul time needs accurate weather forecast as a guarantee.

In addition, the development and utilization of electric energy also has an important relationship with meteorology. For example, solar energy and wind energy, which are called meteorological energy, can generate electricity through conversion. This energy conversion process will not have a negative impact on the environment. Solar energy and wind energy are renewable and can be said to be inexhaustible. At present, all developed countries and even developing countries in the world attach great importance to the development of meteorological energy. In the past 65,438+00 years, wind energy has been the fastest growing energy source in the world. By June 2000, the total installed capacity of global wind power generation had reached14 GW (1GW =10 GW). Among them, German 4644 MW, American 2533 MW, Spanish 18 12 MW, Danish 176 1 MW, Indian 1095 MW and China only have 246 MW. Israel is a country with good solar energy development and utilization. It uses solar heat collecting materials to make solar water heaters, so as to build solar power stations and solve the power supply problem.
