Embodiment Construction
[0013] The technical solutions of the present invention will be further described below through specific examples.
[0014] The invention can be divided into three modules: an IEC61850 client communication module, an IEC61850 client debugging module, and a SCADA dynamic library module. The BerkeleyDB real-time database is a bridge connecting the three.
[0015] 1. The IEC61850 client debugging module uses an XML interpreter to parse the specified SCD file or ICD file into a tree structure, and writes all logical node attributes in the model to the BerkeleyDB real-time database, so that the IEC61850 communication program can obtain relevant information about the SCD model . The IEC61850 client debugging module is designed with an intuitive IED configuration interface, which can configure IED names, access points, instance numbers, IP addresses, report control blocks, etc. for all IEDs in the station, and can display real-time database data in a tree model structure in real tim...

The invention discloses a digital power monitoring system according with an IEC61850 (Communication Networks and Systems in Substations) standard, which establishes a mapping relation of a point-oriented traditional SCADA (Supervisory Control and Data Acquisition) monitoring module and an IEC61850 object-oriented communication technology through a BerkeleyDB real-time database technology. A traditional power monitoring system has an IEC61850 communication function and realizes seamless butt joint with an IED (Intelligent Electronic Device) in a transformer substation; the digital power monitoring system disclosed by the invention can receive and process remote monitoring data, remote signaling data, remote pulse data and the like, and can process control commands of remote control, constant value operation and the like of a background monitoring system downloaded to the IED. In addition, newly changed data can be queried and received in real time through an uploading report service provided through the IEC61850 standard. The digital power monitoring system according with the IEC61850 standard, disclosed by the invention, supports a manner of supporting an SCD (Security Coding Device) or ICD (Interface Control Document) file, can finish communication integration operation of the system after obtaining the ICD files of each factory, and largely reduces field debugging workload.
Description
technical field [0001] In recent years, with the introduction of the IEC61850 protocol standard, domestic digital construction has been vigorously promoted, and the traditional power monitoring system has been unable to adapt to the growing digital substation. Traditional communication protocols such as Modbus, IEC60870-103, CDT, and DNP can no longer meet the technical requirements of digital substations, and will be replaced by digital power monitoring systems that comply with IEC61850 standards. The invention is applicable to intelligent substations and digital substations of various voltage levels, and can realize seamless connection with all IEDs (Intelligent Electronic Devices) in the substation conforming to the IEC61850 standard. Background technique [0002] The IEC61850 standard is a global substation automation standard. It adopts object-oriented modeling technology, abstracts all the functions of the IED into a tree model according to the ICD model file, and uses...
