Problems solved by technology

At present, the commonly used fault detection and diagnosis methods only detect individual components in the power grid information (such as excitation system and its regulator, prime mover and its regulator, synchronous transmitter, and power load), and the detection technology is limited to At the primary level, the detection data only reflects the fault characteristics of a single component, which cannot be measured globally. The fault detection and diagnosis results are too one-sided, making it difficult to improve the reliability of fault diagnosis, which reduces the ability to control power grid information

Description

Technical field [0001] The present invention relates to the technical field of power monitoring, and more specifically to an IoT power monitoring system and method with a wireless sensor network topology structure. Background technique [0002] With the accelerated development of power grid technology and application, the scale of power grid information system and the number of users are increasing, and the grid structure is becoming more and more complex. This puts forward higher requirements for fault diagnosis of the power grid. In power applications, the grid structure and its The operation status is complicated and the grid topology is also confusing, which makes it difficult for users to capture the countless uncertain factors hidden in the grid data when facing the big data of grid faults, which is not conducive to monitoring the healthy and healthy development of the grid. As we all know, in large-scale grid system applications, fault phenomena are very common and unavoid...
