Example Embodiment

[0014] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings: this embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation modes and specific operating procedures are given, but the scope of protection of the present invention is not limited to the following Mentioned examples.

[0015] Such as figure 1 As shown, the system of this embodiment uses a microcomputer and a high-performance computer as a platform, and a computing resource monitoring terminal is introduced between the server and the client to perform computing resource monitoring and computing task scheduling, including: server, client and computing resources On the monitoring side, the server side obtains real-time power system data from the energy management system and stores it in the database server. The data resources of the database server are sent out in two ways, one is sent to the co...

Abstract

The invention relates to a scalable distributed system supporting dynamic security assessment and early warming of a power system, comprising: a server terminal, a client terminal and a computing resource supervision terminal. The server terminal gains real time power system data from an energy management system and saves the real time power system data into a database server. Data resources of the database server are sent in two ways. One is sent to a computing engine server and the other is sent to a data mapping module of a computing engine client off-line calculation. The computing engine server calculation data resources of the server terminal are directly inputted into the computing resource supervision terminal. The client terminal one side is connected with the server terminal to process bidirectional data exchange, and on the other side is connected with the computing resource supervision terminal to realize data bidirectional transmission. The computing resource supervision terminal is separately connected with the server terminal and the client terminal to process bidirectional data exchange. The invention can gain real time system data from the power system to process the dynamic security assessment, so as to find problems in time and give out early warming control strategy.

Description

technical field [0001] The invention relates to a computer system in the technical field of electric power system, in particular to an expandable distributed system supporting dynamic safety assessment and early warning of electric power system. Background technique [0002] With the advancement of modern science and technology, human beings rely on the power system to an astonishing degree. The loss caused by a short power outage is no less than the effect of a major earthquake. Ensuring the safety of the power system has become the relentless pursuit of power workers, but The increasingly complex power system is often difficult to conquer. In recent years, there have been many major power outages around the world. These major power outages have fully exposed the vulnerability of the power grid, and have also sounded the alarm for power workers around the world. The main goal of power system safety assessment and early warning is to reduce the possibility of power system d...
