Embodiment 1
[0016] see figure 1 As shown, it is a schematic flow chart of Embodiment 1 of the online monitoring method for grid equipment of the present invention, which includes steps:
[0017] Step S101: Real-time monitoring of real-time monitoring data of grid equipment, enter step S102;
[0018] Step S102: Generate a corresponding ICD model file according to the real-time monitoring data and set the modeling method, and transmit the model file to the online monitoring server.
[0019] In a specific example of the solution of the present invention, the model file generated according to the solution of the present invention is an ICD (IEC Configuration Description intelligent electronic device configuration description) file, therefore, in the description of the following specific embodiments, the above setting is built The modeling method is called the ICD modeling method, and the generated model file is called the ICD model file. In this ICD modeling method, one LD (Logical Device) c...
Embodiment 2
[0038] see figure 2 As shown, it is a schematic flow chart of Embodiment 2 of the online monitoring method for power grid equipment of the present invention. In this embodiment, the difference from the above-mentioned Embodiment 1 is that this embodiment also includes an online monitoring server that converts the ICD model The modeling process when the file is sent to the remote center.
[0039] Such as figure 2 As shown, the method in this embodiment includes steps:
[0040] Step S201: Real-time monitoring of real-time monitoring data of grid equipment, enter step S202;
[0041] Step S202: Generate a corresponding ICD model file according to the real-time monitoring data and set the ICD modeling method, and transmit the ICD model file to the online monitoring server, and enter step S203;
[0042] Step S203: The online monitoring server generates the ICD model file as an SCD model file according to the set SCD file naming method and the corresponding SCD version descripti...

Abstract
The invention relates to a method for monitoring power grid equipment on line. The method comprises the following steps of: monitoring real-time monitoring data of the power grid equipment; generating a corresponding intelligent electronic device (IED) configuration description (ICD) model file according to the real-time monitoring data and a set ICD modeling mode; transmitting the model file to an on-line monitoring server; generating a substation configuration description (SCD) model file from the ICD model file according to a set SCD file definition mode and a corresponding SCD version description mode; and then transmitting the SCD model file to a remote center. The ICD modeling mode comprises the following steps of: classifying the real-time monitoring data according to a set monitoring data type in a mode of one logic device (LD) corresponding to multiple LDs; and generating the ICD model file from the real-time monitoring data according to the corresponding data definition mode, a corresponding data quality setting mode and a coding mode and the corresponding file definition mode. By the method, the state of the power grid can be evaluated accurately, so that operating stability and reliability of the power grid are improved.
Description
technical field [0001] The invention relates to the technical field of power grids, in particular to an online monitoring method for power grid equipment. Background technique [0002] The safety of equipment is the basis for the safe, reliable and stable operation of the power grid. Effective and accurate monitoring and diagnosis of equipment is an important way to improve the reliability of power supply and the intelligent level of power grid operation. With the continuous expansion of the grid scale, the workload of grid monitoring and operation and maintenance is also increasing, and the technology of remote real-time monitoring and analysis of the working conditions of primary equipment in substations is also becoming more and more popular. [0003] Complete and real real-time monitoring data of equipment is the basis for evaluating equipment status. In the current real-time monitoring scheme for power grid equipment, real-time monitoring data is collected by online mon...
