Abnormal information collection method and system of relay protection equipment

Abstract

The invention discloses an abnormal information collection method and system of relay protection equipment. The method is implemented according to the steps of generating an abnormal information collection script of target relay protection equipment, building an action sequence, building connection with the target relay protection equipment, sequentially issuing each action of the action sequenceto a master processor of the target relay protection equipment, awaiting a response result of returning to execute the action sequence of the master processor of the target relay protection equipment,and storing the response result in a file and displaying abnormal information in an output response result if the response result is received. The system comprises program modules, a client and the target relay protection equipment, wherein the program modules are completely corresponding to the steps of the method, and the client is used for executing the method. By the method and the system, abnormal data can be rapidly and safely acquired by a key, classification and display are provided, an operation and maintenance worker and a factory technician are convenient to timely analyze and diagnose, and a secondary potential risk brought by manual misoperation is prevented.

Description

technical field [0001] The invention relates to relay protection technology, in particular to a method and system for collecting abnormal information of relay protection equipment. Background technique [0002] With the continuous development of the power grid's demand for relay protection functions, the functions of relay protection equipment continue to expand, the hardware and software of the device become more complex, the collection and analysis of device abnormal information is also more specialized, and the professional skills requirements for on-site personnel Higher and higher. In the event of abnormality or hardware failure of the on-site device, it is often difficult for the on-site operation and maintenance personnel to quickly and comprehensively collect device abnormality information, which will inevitably lead to subsequent device defects and hidden danger analysis, resulting in "sick" operation of the protection device. In addition, since the long-term exit ...

Problems solved by technology

In the event of abnormality or hardware failure of the on-site device, it is often difficult for the on-site operation and maintenance personnel to quickly and comprehensively collect device abnormality information, which will inevitably lead to subsequent device defects and hidden danger analysis, resulting in "sick" operation of the protection device

In addition, since the long-term withdrawal of the protection device will cause safety hazards to the stable operation of the power system, the plug-in must be replaced or the device must be reset as soon as possible. At this time, the device can only retain waveform data and simple message information, and cannot retain more complete section information when the device occurs abnormally. data, which may result in the inability to more accurately locate device abnormalities
