What is transmission and distribution?
Author:
Power transmission and transformation refers to the process of delivering electricity from power plants to end-use consumers via substations.
I. Definitions of Power Transmission and Transformation, and Power Transmission and Distribution
Power transmission and transformation refer to the process of delivering electricity from power plants to end-use consumers via substations, in which substations play crucial roles such as electrical energy conversion, voltage transformation, and power distribution. Power transmission and distribution, on the other hand, refers to the process of delivering electricity from substations to residential, commercial, and industrial users through the distribution network, where the distribution network serves the functions of power distribution, control, and assurance.
II. The Roles of Power Transmission and Distribution, and Power Transmission and Distribution Systems
Transmission and transformation, as well as transmission and distribution, are two indispensable links in the power system, and their roles are as follows:
1. Power Transmission and Transformation: High-power electrical energy generated by power plants is converted into appropriate voltage and current levels through substations, enabling its transmission and utilization in the power transmission and distribution process.
2. Transmission and Distribution: The electricity transmitted from substations is delivered to residential, commercial, and industrial users via the distribution network, thereby meeting people’s demand for power.
III. The Difference Between Power Transmission and Transformation and Power Transmission and Distribution
1. Definition: Transmission and transformation refer to the process of delivering electricity from power plants to end-use facilities via substations, while transmission and distribution refer to the process of delivering electricity from substations to residential, commercial, and industrial users through the distribution network.
2. Voltage Levels: The voltage levels used in power transmission and transformation are typically very high, generally ranging from 110 kV, 220 kV, to 500 kV, whereas the voltage levels for power distribution and transmission are relatively lower, usually at 10 kV or 0.4 kV.
3. Technical Requirements: Power transmission and transformation involve technical operations such as power conversion, voltage transformation, and power distribution, which demand high technical expertise. In contrast, power transmission and distribution primarily focus on power allocation, control, and assurance, with relatively lower technical requirements.
