2. Select the rated voltage of the network
It is one of the important issues in the design of power network to determine the power supply range and voltage level of power network and which voltage level is more suitable for power users who require power supply.
3. Select the cross-sectional area of the power line
According to the technical and economic comparison, the wire type and the cross-sectional area of the power network are determined.
4. Determine the wiring scheme of the power network
According to the important degree of power users and the reliability requirements of power supply, a reasonable power supply scheme is put forward, and the main wiring mode of substation and power network is determined. The tasks in the design of power network are interrelated, and only by considering all the factors mentioned above comprehensively can we get a reasonable design scheme.
To meet the requirements of users, a variety of power supply schemes can be used. The design is based on the specific requirements of users, as well as the previous design and operation experience to propose several more feasible schemes, after comparison, choose the more reasonable scheme.
