Description

technical field [0001] The invention relates to the technical field of power transmission, in particular to an energy-saving power transmission system. Background technique [0002] The power delivery system, that is, the power supply system, is a system composed of a power supply system that generates electrical energy and supplies and transmits it to electrical equipment. The power supply system can be roughly divided into three types: TN, IT, and TT, and the TN system is further divided into three forms: TN-C, TN-C, and TN-C-S. [0003] As we all know, in the process of power transmission, a lot of electric energy will be consumed, resulting in energy loss, which is contrary to the energy conservation and emission reduction advocated by the government. Faced with this problem, the main solution is to ensure the stability of power supply and maintain good power quality. In recent years, due to the extensive use of nonlinear loads and the stringent requirements for power ...

Problems solved by technology

In the power system, the root cause of harmonics is due to nonlinear loads. When the current passes through the load, it does not have a linear relationship with the applied voltage, forming a non-sinusoidal wave, thereby generating harmonics, and harmonics The generation of harmonics is the most important factor that affects the increase in energy consumption of the power transmission system. The generation of harmonics will not only affect the quality and quality of power transmission, but the most important thing is to make the transmission line system unstable, increase energy consumption, and greatly increase the transmission power. Reduction, just contrary to the concept of energy saving and emission reduction advocated by the government
