Abstract

The invention discloses a smart power grid distribution type measurement and control synchronizing method. A test terminal with Ethernet networking and a GPS (Global Positioning System) synchronous sequence interface forms a hardware platform together with a server by a known rapid Ethernet exchanger, and the synchronous measurement and control of a distribution type power grid can be realized under the control of a synchronous acquisition and management program, wherein 128 terminals form a distribution type test system and are respectively connected at different parts of transformer substations or factories to complete the local data acquisition, control and processing, and meanwhile, each terminal is managed by a Workstation through a network so as to realize the synchronous control of the local test terminal and other terminals and the data processing by cooperation with the other terminals. According to the smart power grid distribution type measurement and control synchronizing method, the synchronous test between the remote test terminals of the power grid is realized, and the demands on the safety monitoring, grid-tied control and proper scheduling of each station by the distribution type power grid can be met.

Description

technical field [0001] The invention relates to the field of distributed test instruments, in particular to a GPS remote synchronization method for distributed test and control instruments in a smart grid. Background technique [0002] The smart grid is a distributed power grid that needs to solve the grid-connected power generation of various energy sources distributed in different locations. It will put forward more requirements for the safety test and control of the entire grid. The power generation-transformation-distribution stations located in different locations Synchronous monitoring and control between is one of the problems that must be solved. Remote synchronization technology used radio signals earlier. With the emergence of GPS synchronization technology, it began to use the 1 millisecond timing pulse provided by GPS as a synchronization signal to solve the synchronization between two or several stations. Existing methods are difficult to solve the problems of ...
