Embodiment Construction

[0042] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0043] Such as Figure 1-3 As shown, the IEC61850-based on-site relay protection device communication point-to-point method includes the following steps:

[0044] A) Establish communication point-to-point related data sets and data set members under the interface management LD: For point-to-point related data sets, including protection event dsTripInfo, alarm signal dsWarning, and protection remote signal dsRelayDinLD, data objects have been established under PROT and LD0 , there is no need to create it again under the interface management LD. For each FCDA, create the corresponding DO in the interface management LD;

[0045] B) Configure the 61850 model after establishing the communication point-to-point as an ICD file, import it into the template library of the 61850 client point-to-point between the device and the background, sta...

Abstract

The invention discloses a point-to-point communication method for an in-situ relay protection device based on IEC61850, and relates to the technical field of relay protection devices. The present invention includes the following steps: A) establish communication point-related data sets and data set members under the interface management LD, and for each FCDA, establish corresponding DOs in the interface management LD; B) import the 61850 model into an ICD file after configuration In the template library of the 61850 client that the device and the background point to each other; C) start the 61850 server of the device, communicate with the 61850 client through the MMS protocol, and the 61850 client obtains the 61850 model, and communicate with the point-to-point according to the relevant DO in the interface management LD , the communication point is controlled by the 61850 service control CPU / HMI, and the report is sent by the HMI for point-to-point communication, and the situation of the actual report of the simulation device occurs. The communication point-to-point method of this technical solution controls the CPU / HMI through the 61850 service, after the actual verification of the CPU / HMI, and can point-to-point to the event type signal point of the device, which solves the defects of the existing 61850 communication point-to-point method, Easy to operate and good versatility.

Description

technical field [0001] The invention relates to the technical field of relay protection devices, in particular to an IEC61850-based communication point-to-point method for in-situ relay protection devices. Background technique [0002] At present, the main significance of point-to-point communication is to ensure that the events, alarms, and remote signaling triggered by the CPU / HMI of the device are consistent with the content sent to the background by the 61850 service. The traditional device has a liquid crystal panel, enters the corresponding menu to simulate and trigger the corresponding signal, and sends it to the background through the MMS layer network to confirm the consistency of the content. [0003] The on-site relay protection device is close to the primary equipment without protective installation, affected by electromagnetic, climate environment, etc., and has no LCD panel. The operation of the device can only be realized remotely, and the corresponding device...
