Problems solved by technology

The network of the distribution network is complex, with a large amount of equipment and frequent changes, which cause many problems for the application functions related to the analysis of the distribution network network
On the one hand, distribution network dispatchers cannot accurately analyze the impact of dispatching operations on the power grid; on the other hand, the operation plan drawn up by distribution network dispatchers is no longer correct due to changes in the distribution network operation mode
Wrong scheduling operations can easily lead to power loss for users and reduce the reliability of the power grid

Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] The entire power monitoring system needs to abstract the actual power grid into specific devices such as switches, loads, power supplies, etc. There are topological connections between these devices.

[0036] like figure 1 As shown, the pre-operation simulation operating system of the present invention is connected to the power monitoring system, and includes four modules: a fast simulation startup module, a pre-operation execution module, a pre-operation analysis module, and an analysis result display module.

[0037] The fast simulation startup module is responsible for initializing the pre-operational simulation system, such as figure 2 As shown in , after the fast simulation startup module is started, it will sequentially check whether the fast simulation state is started, whether the fast simulation function is available...

Abstract

The invention discloses a pre-operation simulation system for a power distribution network and a simulation analysis method. The simulation system comprises a quick simulation starting module, a pre-operation execution module, a pre-operation analysis module and an analysis result display module. During simulation analysis and summer peak load period analysis, simulation operation is performed according to a scheduling operation scheme and is subjected to distribution network load flow calculation and distribution network risk assessment, the change of relevant power distribution network electrical amount caused by the simulation operation and the increased or decreased power network operating risk are displayed through a pre-operation simulation screen in contrast to a real-time interface screen, the result information of influence on the safety, reliability and economy of a power network after pre-operation is provided, and an aid decision is provided for a scheduler.

Description

technical field [0001] The invention relates to the field of simulation technology of distribution automation systems, in particular to a pre-operation simulation system and a simulation analysis method of a distribution network. Background technique [0002] The distribution network is an important part of the power system, and its safety and reliability will directly affect the development of the national economy and people's living standards. The distribution network has a complex network, a large amount of equipment, and frequent changes, which cause many problems for the application functions related to distribution network analysis. On the one hand, the distribution network dispatcher cannot accurately analyze the impact of dispatching operations on the power grid; on the other hand, the operation plan drawn up by the distribution network dispatcher is no longer correct due to the change of the distribution network operation mode. Wrong scheduling operations can easil...
