If your problem is developed, it will be an evaluation engineer's paper. During the 30 years that our company has been engaged in the production and sales of R&D and reactive power compensation equipment, employees of grass-roots power supply stations often ask similar questions. In short, the conclusion is this:
1. From the power supply terminal to the user terminal, the higher the power factor of the user terminal, the lower the line loss caused by the power factor problem, the higher the equipment efficiency of the power supply terminal, the better the benefit of the power supply enterprise and the higher the security of the power grid. Therefore, it is of great benefit to reduce the line loss to improve the power factor of each power saving in the power supply line as much as possible.
2. Line loss, in addition to power factor, is also related to many line technologies, such as conductor, line diameter, line length, whether the line connection is tight and so on. These are easy to understand, but the impact on line loss may be greater than the impact on power factor, which requires special attention.
3. One characteristic of rural power grid is that the low-voltage lines are particularly long. If users use a lot of electricity, such as irrigation with electricity, or simply processing with a motor, the power factor of the motor is relatively low, so the line voltage drop is great and the line loss is also great. We have seen extreme cases: the voltage of 220V is less than 150V at the customer end, which is equivalent to 30% of the electric energy, and it is lost on the line. Therefore, improving the power factor of agricultural equipment plays a very significant role in reducing line loss.
Don't expand, or you will write a paper.
Reactive power compensation is an energy-saving technology advocated by the state, but it is very professional and needs professionals to do it. More questions and information about reactive power compensation and power factor can be found and discussed here. There are a group of old electricians who have gone to college, but they all take pleasure in helping young people. :zhidao.baidu.com/uteam/view? . teamId = 36954
