Capacity issue of 110,000 stations
Thread Content
Capacity issue for 110,000 stations: In the project planning, if 110,000 stations are to serve as the company’s main substations, by how much should the capacity of these stations exceed the designed load of the areas they supply with electricity? What standards are primarily used as a basis? If the reserved load is high, apart from the higher equipment investment and less economical operation, are there any other additional costs that need to be paid? Please give me some advice!
It needs to be determined based on the nature of the electrical load. Small and medium-sized factories are generally classified as having a level 2 load. Once the calculated load for the entire factory is known, the capacity of a transformer should be sufficient to handle that load; in such cases, it is appropriate to use the nearest higher-level transformer. Choosing a transformer that is too large results in high investment costs and elevated basic electricity charges, leading to uneconomical operation. It also causes high short-circuit currents at all levels, posing significant risks ； The cross-sectional area of 10kV cables has increased.
