Data processing system and message method based on IPC (industrial personal computer) synchronized phasor measurement unit

Abstract

The invention relates to a data processing system and a message method based on an IPC (industrial personal computer) synchronized phasor measurement unit, aiming to enable the synchronized phasor measurement unit to be in accordance with 61850 standards. The system adopts an embedded software and hardware platform and realizes the functions of device modeling receiving and analysis of sampling value messages, in-station monitoring and other IED equipment data shared functions, which is in accordance with IEC (international electrotechnical commission) 61850 standards, based on that the functions of phasor calculation, fault record, real-time record and analysis, real-time communication and the like of the conventional synchronized phasor measurement unit are realized. By adopting the system and the method provided by the invention, the high-speed and stable communication network design can be realized and the monitoring of dynamic characteristics of the system can also be realized, the obtained data have high density and high instantaneity.

Description

Technical field: [0001] The invention relates to the field of power systems, in particular to a data processing system and a message method based on an industrial computer-based synchronized phasor measuring device. Background technique: [0002] At present, the construction of smart grid is a hot spot in the power industry of various countries. my country has proposed to build a smart grid with Chinese characteristics that is "strong and reliable, economical and efficient, clean and environmentally friendly, transparent and open, and friendly and interactive". Smart substation is an important part of smart grid. Smart substation refers to the application of advanced, reliable and highly integrated equipment. Through networked communication and standardized information platform, it can realize comprehensive collection of power grid operation data, automatic operation control, online analysis and decision-making, and collaborative interaction. Substations with functions such ...

Problems solved by technology

[0003] The intelligent integrated components that realize the functions of measurement, control, and protection in smart substations are an indispensable part of them. However, at present, these devices generally have defects such as the inability to provide absolutely accurate time-scale data, insufficient data accuracy, and low collection density.

Since the appearance of the synchrophasor measurement unit (PMU, Phasor Measurement Unit) in the 1990s, it has been widely used because of its high measurement accuracy, precise time scale, and fast data transmission rate, and has gradually It is a trend to replace traditional measurement equipment, but currently it is only used in conventional substations due to high requirements for sampling rate and timing accuracy, so developing a synchrophasor measurement device suitable for smart substations has become an urgent task Work
