Problems solved by technology

However, the maintenance and debugging of power flow calculation is a relatively heavy work, especially the debugging of ring network power flow is one of the difficulties. If the power grid is relatively large, the work of maintaining power flow will be even more difficult

Embodiment 1

[0031] Embodiment 1: Search for an example of a node branch model inside a plant.

[0032] Enter the 220kV1M bus ID of Toyama Station: 27318, the maximum number of floors: 5, then select "Search only this station", select "Search main transformer", select all voltage levels, and then perform "Search" to get figure 1 As shown in the graph, the 220kV bus of Fushan Station runs with 1#, 2#, and 3# main transformers, the 110kV side of the main transformer runs in parallel, and the 10kV side runs in parallel.

Embodiment 2

[0033] Embodiment 2: On the basis of Embodiment 1, select "only display ring" and search again, then as figure 2 It shows that there is only the electromagnetic loop of this station.

Embodiment 3

[0034] Embodiment 3: On the basis of Embodiment 2, only select 220kV for the voltage level, do not select "only search this station", and then search, then only the loop formed by the line is displayed, such as image 3 shown.

Abstract

The invention provides a visual debugging method for electric power system looped network load flow calculation. By means of searching for a power grid topology model and imaging the power grid topology model, the structure and the current running conditions of a power grid are reflected visually. The visual debugging method is applied to electric power system planning and design and real-time monitoring of the electric power system running state, so that complex looped network load flow calculation and debugging work is greatly simplified, the load flow maintenance work is simplified substantially, and the debugging efficiency is improved.

Description

[0001] technical field [0002] The invention relates to a power flow calculation method of a power system, belonging to the technical field of power system automation. Background technique [0003] With the continuous improvement of power system automation level, the role of power flow calculation is becoming more and more prominent. In the study of power system operation mode and planning scheme, power flow calculation is required to compare the feasibility, reliability and economy of the operation mode or planning power supply scheme. At the same time, in order to monitor the operating status of the power system in real time, a large number of fast power flow calculations are also required. Therefore, power flow calculation is the most widely used, basic and important electrical calculation in power system. When planning and designing the system and arranging the operation mode of the system, the offline power flow calculation is used; in the real-time monitoring of the...
