The role of power transmission and distribution in the State Grid

1. Power transmission: The transmission network distribution system is able to transmit the electrical energy generated by power plants through transmission lines and substations, and reduce the voltage of the electrical energy to a suitable voltage through distribution transformers at appropriate locations.

2. Power dispatching: The transmission network distribution system can intelligently dispatch and control power according to factors such as power demand and power supply pressure to ensure power supply quality, power supply safety and stable operation of the power system.

3. Power protection: The transmission network distribution system can ensure the safe operation of power system equipment during the transmission process through a series of measures such as equipment protection and fault handling.

4. Power quality: The power transmission network and distribution system can improve power quality, reduce voltage drop, and avoid power fluctuations and harmonics during power transmission by optimizing equipment configuration and technical measures.

5. Energy saving: The transmission network and distribution system can realize intelligent dispatching and energy management according to electricity demand, promote the balance of supply and demand, reduce electricity costs and save energy.

In short, the transmission and distribution system of the power grid plays a very critical role in the stable operation and safe power supply of the power system. It can realize multiple functions such as power transmission, dispatching, protection, optimization and conservation, and provide guarantee for economic and social development.
