Embodiment

[0029] The configuration diagram of the static security analysis system using the power grid (see figure 1 ). According to the function, the overall hardware structure of the system can be divided into computer network and data acquisition module, real-time monitoring and control module, historical data storage module, static security analysis module, network security equipment and terminal workstation. Wherein, the software implementation flowchart of core algorithm module (see figure 2 ) fully explained the working principle and process of the static security analysis module, and the algorithm program flow chart for modeling and calculation analysis of the data processed by the static security analysis module (see image 3 ).

[0030] The real-time data collected by the computer network and the data acquisition module is received by the RTU server and preprocessed by the front-end computer, and then sent to the real-time monitoring and control module through the optical f...

Abstract

The invention belongs to the technical field of applications of analysis methods of power grid dispatching decisions. The system utilizes hardware environments, support platform software and data platform software of a power grid dispatching decision support system, wherein a hardware part can be divided into a computer network, a data acquisition part, a real-time monitoring and control part, a historical data storage part, a static safety analysis part, a network safety device, dispatcher workstations, a maintenance workstation and the like; and the software of the system adopts a WINDOWS system, simulation analysis software power system analysis software package (PSASP) and an advanced support platform. Real-time data acquired by a computer and data acquisition module are transferred to the real time monitoring and control module to perform various treatment and conversion by communicating with a communication server; correlated data and parameters are stored into a historical data storage module, finally, a machine operating power grid advanced application software serve as a terminal workstation and a client, an optional scheme is provided for operation personnel and dispatchers through a man-machine dialogue window, potential unstable factors in the power grid are studied in advance and out-of-limit conditions of the system are eliminated.

Description

technical field [0001] The invention belongs to the technical field of application of calculation and analysis methods for dispatching decisions of enterprise power grids, and relates to a static security analysis system for modularized power grids based on a communication system. The modular grid and software system of the application communication system is combined with the security analysis method. Background technique [0002] In order to cooperate with the production project of the enterprise, the enterprise needs to expand the power load and the capacity of the power grid at the same time. At this point, the system becomes more complex, and the probability of failure increases, and certain disturbances may cause large-scale blackouts and acute stability problems. Especially when stability damage and uncontrollable chain reactions of deterioration occur, the power outage will have a large scope and long duration, which will have inestimable and serious consequences no...
