Power grid continuous operation simulation section generation method and system

Abstract

The invention provides a power grid continuous operation simulation section generation method and system. The method comprises the following steps of acquiring power grid model data; acquiring historical power flow data, and matching the historical power flow data with the power grid model data, and generating initial data sections; generating a continuous scene data section based on the pluralityof initial data sections; and adjusting the continuous scene data section, and generating a continuous operation simulation section. According to the method and system, the section initial values areadjusted through technologies, such as distribution, adjustment, optimization adjustment and the like, so that the convergence and the accuracy of power flow calculation are improved, and the usability of the power flow data section is further improved; the simulated section set for simulating the continuous operation of the power grid is provided, so that effective data support is provided for testing and verifying of the analysis application software of a dispatching automation system, the effectiveness and reliability of the analysis software are improved, and safe and stable operation ofthe dispatching automation system is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to a method and a system for generating a continuous operation simulation section of a power grid. Background technique [0002] The power system consists of generators, loads, lines, transformers, switches, switches, busbars, capacitive reactance, DC systems and other equipment for power generation, transmission, transformation, and consumption. During the operation of the power system, the power load fluctuates momentarily due to human activities, and the intermittent and uncertain power generation of new energy leads to the imbalance of system power. The power generation needs to automatically track the change of load during the entire operation process to maintain the power system. The power balance and frequency stability of the system, while the system may have faults with different influence ranges, resulting in changes in the operating structure of the pow...

Problems solved by technology

[0003] At present, when dispatching automation systems and various application software testing and acceptance, the preparation of data sections is time-consuming and laborious, and is very limited

The power grid model is generally small during the test, and the operation mode data is derived from the site or manually set static sections, which is poor in authenticity and cannot reflect the change process. The test case is temporarily prepared for the acceptance outline, and the test effect is severely limited, and it is difficult to reflect the system or software. Defects, functional testing cannot be carried out effectively
