In the power system, the long-distance power transmission and transformation system has the following characteristics:
High voltage level: Long-distance power transmission usually uses higher voltage levels, such as 500kV, 1100kV, etc., to reduce line losses and line costs.
The longer the line, the greater the loss: The power loss of long-distance power transmission is high, and special measures need to be taken, such as using high-voltage transmission and reasonable layout of lines, to reduce power losses.
High requirements for insulation and anti-corrosion: Due to the long lines, insulation materials and anti-corrosion treatment are particularly important to ensure stable operation of the system.
Advanced control and protection systems are required: Long-distance power transmission requires higher control and protection systems to cope with various complex situations and ensure the reliability of power transmission.
When building and using long-distance power transmission and transformation systems, the following points need to be noted:
Ensure safe and stable operation: It is necessary to consider the impact of factors such as lightning and overvoltage on transmission lines, and take effective measures to reduce the risk of accidents.
Consider environmental impact: The construction of transmission lines should minimize the impact on the ecological environment, and take restoration and compensation measures.
Investment and operating costs: The construction and operating costs of long-distance transmission systems are high, and cost-benefit analysis is required.
