METHOD AND SYSTEM FOR THE COMPLEX ON-LINE MONITORING OF HIGH-VOLTAGE ELECTRIC SUBSTATIONS

摘要

The invention relates to a method and a system for the on-line monitoring of a high-voltage electric substation. According to the invention, the method consists in monitoring the technical condition and the functional parameters of high-voltage electrical equipments in a substation, with a view to detecting faults in a primary stage, informing the customer accordingly as well as storing said data and transmitting the same to a centralized data base with the view of the assets management. The claimed monitoring system consists of a first analogical alternating current input block (2), a second alternating voltage input block (3), a third unified signal input block (4) and a fourth digital input block (5), a data acquisition system (6) provided with data and signals memory (7) and a real-time clock (8) communicating with an expert system (9) consisting of a data processing block (10), a knowledge base (11) containing a data base and a system of rules, an inference motor block (12) and a block (13) ensuring the interface with other systems, the information processed by the expert system (9) being transmitted to a digital output interface (14) and a system of relays (15) permitting adaptation to some control, protection and signalling circuits of an electric substation.
