Embodiment Construction

[0019] The data access method from the converter station fault recording system to the IEC61850 fault recording master station uses virtual modeling technology to model the professional fault recording device in the converter station and the built-in fault recording modules of all control and protection devices as The fault recording logic device LD (Logical Device) inside the intelligent gateway is based on network folder sharing, adopts network directory mapping and file redirection methods for unified centralized management, real-time detection, and supports file service interface definition and implementation by extending IEC61850 Recording files are queried and extracted according to time periods, realizing efficient communication with the IEC61850 fault recording master station system in the dispatch center.

[0020] Network directory mapping: map network shared folders of different hosts to local directories.

[0021] File redirection: When the intelligent gateway detec...

Abstract

The invention relates to a method for accessing data to an IEC61850 fault recording master station from a converter station recording system. The method is characterized by comprising the steps that fault recording data areas of a professional fault recording device and all control and protection devices in a converter station are monitored by adopting a network directory mapping mode based on virtual modeling technologies, the professional fault recording device and all of the direct current transmission control and protection devices with a built-in fault recording function in the converter station are modeled into intelligent fault recording logic devices (LDs) conforming to IEC61850 standards, an intelligent gateway detects file generation of the fault recording data areas of all of the devices in real time and is responsible for real-time efficient communication with a fault recording master station system adopting the IEC61850 standards in a dispatching center, thereby ensuring the power grid dispatching center to acquire operational analysis data of key operations, abnormal situations and the like in the direct current transmission converter station timely and rapidly.

Description

technical field [0001] The invention relates to a data access method from a fault wave recording system of a converter station adopting the IEC61850 standard to a fault wave recording master station system. Background technique [0002] The control and protection system of DC transmission project realizes the control and protection of all equipment of DC transmission, including: pole control, station control (AC field / DC field), DC system protection, converter transformer control and protection, AC / DC filter control and protection , Converter cooling system control and protection, station power system control and protection, etc. The control and protection devices of different manufacturers are implemented by general-purpose or dedicated advanced controllers. Although domestic and foreign manufacturers are currently developing or claiming to have completed the research and development of digital intelligent converter stations, the DC transmission projects that have been put ...
