Abstract

The invention discloses an intelligent security and protection early-warning system comprising a power supply, a processor, a memory device and an alarm device. The power supply is connected with the input terminal of the processor electrically; a wireless communication module and a remote monitoring terminal are in signal connection; the processor is connected with a sensor assembly by a signal acquisition and processing unit; and the output terminal of the processor is connected with an electric fire monitoring device by a protocol conversion module. Compared with the traditional security and protection early-warning system, the provided system has the following beneficial effects: the electric fire monitoring device employs an improved HHT technology to detect harmonic waves; an APF filter having a fast response speed is connected in parallel to suppress series-parallel connection resonance, thereby realizing dynamic compensation. An active filter device has advantages of a PPF and an APF, so that multiple harmonic waves can be suppressed effectively and reactive compensation can be provided. The system is suitable for high-voltage distribution network.

Description

technical field [0001] The invention belongs to the technical field of electric power monitoring, and in particular relates to an intelligent security early warning system. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, people's demand for electric energy continues to increase, and the requirements for safe power supply are also getting higher and higher. The formation of large-scale and integrated national power grids; the gradual enhancement of inter-regional interconnection; the continuous increase of stand-alone capacity and total system capacity; the formation of large-scale power systems; the construction of new energy power systems; appear; making the structure and operation of the power system more and more complex. The complexity of the power system directly threatens the safe and stable operation of the system. Some local disturbances may lead to blackouts or sharpen the stabilit...
