Abstract

The invention provides an electric power security integrated monitoring device which is characterized in that a sensor set, a preprocessing module, an electric power quality analyzing module, a microprocessor, a storage and a communication module are included, the sensor set comprises a plurality of sensors and is used for collecting operation parameters of electric equipment, the preprocessing module preprocesses the operation parameters, the electric power quality analyzing module analyzes electric power quality and transmits electric power quality parameters to the microprocessor which analyzes the security state of a power grid and the electric equipment and electric fire hidden hazards according to comparing results of the electric power quality parameters, the preprocessed operation parameters and electric security data, and a fire warning signal is sent. When the device is used independently, electric energy quality and electric fire hidden hazards of local potential can be monitored on line in real time, during networking, the device can be used as a data collecting device and a data preprocessing module of an electric power security monitoring system, and data transmission amount and system information processing amount are lowered.

Description

technical field [0001] The invention relates to the field of power system operation monitoring, in particular to a power safety comprehensive monitoring device and an analysis method thereof. Background technique [0002] The existing safety monitoring instruments have a single function. The power monitoring instruments focus on the monitoring of basic power parameters, while the electrical fire monitoring instruments focus on the monitoring of flue gas and temperature, and have no monitoring effect on electrical fires caused by power quality problems. At present, there is no effective monitoring instrument that can not only conduct real-time online monitoring of local potential power quality and electrical fire hazards, but also can be used as a data acquisition device and data preprocessing module of the power safety monitoring system to reduce the amount of data transmission and the system. amount of information processing. SUMMARY OF THE INVENTION [0003] Aiming at t...
