Abstract

The invention provides a micro synchronous phasor measuring device for a power distribution network. The device comprises a bus, a CPU module, at least one analog quantity acquisition module, an intelligent IO module, a time synchronization module and a time keeping module, wherein the bus is a composite cable of a power bus and a communication bus, the analog quantity acquisition module is connected with the communication bus in the bus through a connector, and transmits acquired data back to the CPU module through the communication bus, and the CPU module comprises a processor system PS anda programmable logic PL which perform data interaction through an AXI communication interface. The device is advantaged in that all the functional modules are connected with the bus through the connectors, a plug-in hardware structure is achieved, configuration of the structure is convenient and flexible, the plug-in hardware structure can be configured to flexibly configure an analog acquisitionloop only for the single-interval/ring main unit six-interval measurement requirement of a distribution network line, based on the design, the size of the micro synchronous phasor measuring device forthe power distribution network is reduced, and the installation space is effectively saved.

Description

technical field [0001] The invention belongs to the technical field of power distribution automation, and in particular relates to a miniature synchronized phasor measuring device for a power distribution network. Background technique [0002] With the continuous development of new energy technologies and the increasing demand for electricity, building a strong smart grid has become the future direction of development. Among them, the automation of smart distribution network is an important part of smart grid construction. It is an important means to improve power supply quality, improve power supply reliability, expand power supply capacity, and realize efficient and economical operation of distribution network. one of the foundations. my country's distribution network has a large scale, complex environment, and high failure rate. Therefore, the monitoring and control of the distribution network's operating status is of great significance to the efficient and economical op...
