Power consumption condition monitoring method and system

Abstract

The invention discloses a power consumption condition monitoring method. The power consumption condition monitoring method includes installing a monitoring device at the predetermined position of a monitored object; acquiring the electric quantity of the monitored object acquired by the monitoring device, and calculating the value of each predetermined power consumption parameter of the monitored object in the measuring period based on the electric quantity; comparing the value of each predetermined power consumption parameter with the corresponding threshold of the predetermined power consumption parameter to obtain a comparison result; and executing the corresponding control operation on the monitored object based on the comparison result. By installing the monitoring device at the predetermined position of the monitored object, the electric quantity of the monitored object can be obtained in real time; the informationization, visualization and controllability of the dynamic process of energy consumption can be realized, the energy consumption structure, process, and elements during the enterprise production process can be managed, controlled and optimized, and the energy use efficiency is improved. The invention further discloses a power consumption condition monitoring system.

Description

technical field [0001] The invention relates to the technical field of electrical systems, in particular to a method and system for monitoring electricity consumption conditions. Background technique [0002] While China's economy continues to grow at a high speed, it is also accompanied by huge pressure from energy shortages and environmental degradation. The most effective and economical way to face this challenge is to build energy consumption monitoring, management, and control systems in high-energy-consuming enterprises. Innovate to improve the efficiency of energy use and help enterprises achieve the goals of energy saving, efficiency enhancement and clean production. [0003] According to statistics: more than 10% of the annual energy loss of large-scale power-consuming enterprises comes from the lack of energy monitoring and maintenance plans, and 12% of the annual energy loss comes from the lack of energy management and control systems. In addition to the extensiv...

Problems solved by technology

[0004] The power consumption status of power users and the power load of public station areas fluctuate greatly with time. The asynchrony and imbalance of power consumption make the distribution and adjustment of power consumption have a large room for optimization and improvement. Due to the lack of reasonable and simple The identification method and real-time monitoring tools are not installed because of the high investment cost, and there is no good manual method and management means to implement tracking and statistical analysis at any time, so the power consumption behavior can only be controlled in a vague or approximate way Or power distribution, failed to achieve the goal of optimizing power consumption and reducing losses, local overload, excessive power consumption often occurred, and even safety accidents such as tripping and fire occurred
