Embodiment 1

[0063] The system applying the fast distribution network simulation method of the present invention performs the following operations after being powered on and started:

[0064] 1. Read in the original physical model, load planning curve, operation mode change event table, equipment change event table and simulation control information. Specifically, the physical model, load planning curve, operation mode change event table, and equipment change event table are stored in special disk files. The physical model file mainly stores the following information device ID (keyword), name, type node number, node 0 number, node 1 number, node 2 number. The network connection relationship reflected by the node number.

[0065] 2. Form a power grid calculation model based on the physical model. Specifically, the program automatically generates calculation models based on physical models: forming calculation models of power sources, busbars, switches, loads, and lines. Specifically, the...

Embodiment 2

[0074] Embodiment two, such as image 3 As shown, the fast simulation method for distribution network of the present invention includes the following steps:

Abstract

The invention provides a quick simulation method and device of a distribution network, a storage medium and computer equipment thereof. The quick simulation method includes: according to a preset simulation period and preset critical measurement, performing simulation on the distribution network and acquiring running parameters of the distribution network corresponding to the current simulation period; establishing a calculation model of the distribution network and performing network topology analysis on the calculation model of the distribution network to form a network power supply level relation; on the basis of the network power supply level relation, performing forward thrust generation trend calculation to acquire power flow calculation results; if the current simulation period is not the final period of the preset simulation period, returning to the step to require the running parameters of the distribution network, corresponding to the current simulation period, and performing the operation cyclically to finally acquire key measurement data of the distribution network subjected to simulation in the preset simulation period. During the entire process, the running status of changing in two dimensions of time and preset critical measurement can be rapidly simulated, and quick simulation of the distribution network is realized.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a fast simulation method, device, storage medium and computer equipment for a distribution network. Background technique [0002] The distribution network is the grid closest to the user in the entire grid structure. The power supply reliability, power supply quality, and power supply volume of the grid are all reflected through the distribution network. Whether the network structure is reasonable is the key factor that determines the quality of the distribution network. one.
