Intelligent transformer networked measurement and control system and method

Abstract

The invention discloses an intelligent transformer networked measurement and control system and an intelligent transformer networked measurement and control method in the technical field of intelligent transformer secondary control. The system comprises a clock synchronization module, a process layer network module, a station control layer network module, a programmable logic module and a central control module, wherein the clock synchronization module is connected with the process layer network module and outputs clock synchronization output information; the process layer network module is connected with the programmable logic module and the central control module respectively and outputs each interval analog quantity and switch quantity information and local real-time information; the programmable logic module is connected with the central control module and outputs a control rule algorithm; and the station control layer network module is connected with the central control module, receives an anti-operation lockout rule algorithm and a strategy optimization algorithm and outputs system configuration description (SCD) files from a monitoring background system. According to the system and the method, networked measurement and control can cover a plurality of intervals and even the whole station, so that highly integrated application of an intelligent transformer based on a networked information sharing mechanism is realized; and therefore, the system and the method contribute to optimizing a system configuration scheme, reducing system failure rate and improving system stability.

Description

technical field [0001] The invention relates to a device and method in the technical field of secondary control of an intelligent substation, in particular to a networked measurement and control system for an intelligent substation and a method thereof. Background technique [0002] The IEC61850 system provides a substation information flow architecture system for the advancement of smart substation technology engineering. The "three-layer, two-network" structure has become an important feature of smart substations that are different from conventional substations. Information "collected in one place and shared by the whole station" fully reflects the The convenience of "on-demand calling" of smart substation information constitutes the basis of a "self-healing" smart grid. [0003] With the advancement of smart substation technology, localization of relay protection devices will become an inevitable development trend. The main reason is that primary and secondary equipment c...
