Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] like figure 1 As shown, the intelligent computing grid of the online voltage stability safety assessment system of the present invention is under Intranet (Ethernet Local Area Network) or Internet (Wide Area Internet) network environment, by relational database system 1, Web server 2 and the coordination proposed in conjunction with the present invention Computing grid composed of manager engine 4 , computing manager engine 3 , plus computing node engine 7 , monitoring client engine 5 and terminal browser 6 .

[0032] The coordination manager engine 4 is responsible for communicating with the power system data acquisition / energy management system (SCADA / EMS-Supervisory Control and Data Acquisition / Energy Management System) 8, receiving the real-time state estimation section data of the power grid, controlling the calculation manager engine 3, and coordinating ...

Abstract

A grid implementation method for an online voltage stability safety assessment system, comprising the steps of: ①Building a computing grid in a network environment according to computing requirements; ②The coordination manager engine obtains real-time state estimation section data from a SCADA / EMS system; ③Computing The manager engine performs power flow convergence verification on the real-time state estimation section data to form a computing task pool; ④ each computing node engine applies for computing; The mixed voltage stability index information affected by power load is identified by sorting the weak nodes of the power grid; ⑥ The information of the identified weak nodes of the power grid is written into the database, which is refreshed periodically, and the voltage stability safety assessment results are displayed in graphs. This method can maximize the computing power of each computing node, can effectively realize dynamic load balancing, and has good dynamic scalability and fault tolerance.

Description

technical field [0001] The invention relates to a safety and stability evaluation method applied in power system operation and safety monitoring systems, and belongs to the technical field of computer technology applied to power dispatching automation. Background technique [0002] In recent years, with the continuous growth of load demand, the power system is gradually entering the era of long-distance, large-capacity, ultra-high voltage transmission, which can optimize resource allocation, improve power generation efficiency, and enhance power supply reliability. However, the structure of the power system is becoming more and more complex, and the complexity of scheduling increases accordingly, and the stability of the system becomes more prominent. In particular, the system reforms of breaking monopoly, deregulation, introducing competition, and establishing a power market in the power industry force power companies to make full use of existing equipment to pursue an eco...
