Abstract:

In order to solve the problem that the current domestic and foreign electrical calculation methods have too high requirements for the input parameters of the planning power grid, the predicted load of the plot was transformed into the electrical calculation load, and the realization method of spatial distribution of the future load of the plot was proposed. On the basis of studying the classical reliability formula, the concept of comprehensive failure rate was proposed. Moreover, a more practical reliability engineering calculation formula was given, which simplifies the use conditions of the classical formula. The core algorithms of electrical integration calculation (including power flow, short circuit, reliability and N-1 verification), load forecasting and load space allocation algorithm were applied in the grid planning project of Dezhou Jinghua. The results show that the engineering implementation method is accurate and fast, and can meet the needs of power grid planning.

Key words: power grid planning, load forecasting, load space allocation, power flow calculation, short circuit calculation, reliability calculation, N-1 check
