Research on electrical load calculation of civil building

The current civil building electrical load calculation is represented by the demand coefficient method,and the load calculation is carried out through key parameters such as the demand factor, dispersion factor, and coincidence factor specified in the specification. In recent years, this method has been unreasonable in the power supply and distribution design of civil buildings, which is embodied in the conservative selection of transformers.Given that the current civil building energy consumption system has generated a large amount of energy consumption data, these data can be used in turn to calculate the load of new buildings. This paper proposes a new load calculation model, which uses the existing building energy consumption big data, and uses the clustering algorithm to calculate the load of new buildings. Based on this idea, this paper designs a complete data classification and load calculation process, and verifies the model through specific projects. In the verification project, the transformer configuration obtained by the new load calculation model saves 37.5% of the capacity compared with the traditional method. The calculation method is also beneficial for blockchain applications of energy consumption data.
