Embodiment
[0019] figure 1 It is a specific implementation flow chart of the IEC61850-based smart substation alarm intelligent analysis method of the present invention. Such as figure 1 As shown, the specific steps of the smart substation alarm intelligent analysis method based on IEC61850 of the present invention include:
[0020] S101: Generate a protection logic expression:
[0021] The smart device protection logic in the smart substation given by the manufacturer obtains the function and function impact factor of the smart device. The function impact factor is the report that can affect the functions in the function set of the smart device and is described in the data set in the system configuration file SCD of the whole station. In this paper, the smart device function set is the function set of the smart device that will be affected by the pressure plate, control word and alarm, and then generate the functional logic expression of the protection logic, that is, the AND between a...

The invention discloses an intelligent substation alarm intelligent analysis method based on IEC61850. The function and function influence factors of intelligent equipment are acquired by the intelligent equipment protection logic in an intelligent transformer substation given by the manufacturer, the function logic expression of the protection logic is generated, and whether the state of the function influence factor is changed or not is judged according to the message information. If the state is changed, the function logic expression with the function influence factor effect is obtained, and the result of the function logic expression is obtained through calculation. The result of the function state obtained in advance is matched to obtain the current state of the function. Finally, fault positioning is carried out, and the equipment which is affected by the alarm events is identified. The method can be adapted to alarm diagnosis and fault positioning of different intelligent substations, and can help operation and maintenance personnel to find faults or hidden dangers in time.
Description
technical field [0001] The invention belongs to the technical field of intelligent substations, and more specifically relates to an intelligent analysis method for alarms of intelligent substations based on IEC61850. Background technique [0002] With the development of economy and progress of society, people's demand for electric energy continues to increase. With the country's strict control of environmental supervision and the introduction of energy policies, the requirements for power quality are also increasing. The introduction of distributed energy has made it difficult for traditional power networks to meet the requirements of development. As an important part of national economic development and energy policy, smart grid has played a huge role in promoting the development of renewable energy and low-carbon economy. As an important node of the smart grid, the smart substation has also attracted people's attention. [0003] Compared with the traditional substation,...
