Abstract

The present invention relates to the field of electric power technology, and provides a method and system for power load decomposition based on current waveform characteristics. The method includes: obtaining the electrical characteristic parameters of each power-consuming equipment contained in the monitored power load range under each working state when it is running stably, And save the extracted electrical characteristic parameters into the pre-generated load characteristic database; online real-time monitoring of voltage, current and power parameters at the power load port, power parameters include the total active power and total active power of electrical equipment within the monitored power load range Total reactive power; according to the online monitoring of the total current parameters at the electrical load port, the monitored electrical load is decomposed, and the existence coefficient of each working state of the electrical equipment within the monitored electrical load range is calculated, thereby effectively Realize the power load decomposition, and determine the power consumption ratio of different electrical equipment, and further realize the refinement of energy consumption management.

Description

technical field [0001] The invention belongs to the field of electric power technology, and in particular relates to an electric load decomposition method and system based on current waveform characteristics. Background technique [0002] Non-invasive load monitoring (Non-intrusive Load Monitoring, NILM) or load disaggregation (Load Disaggregation, LD) is a novel power load detail monitoring technology, which can monitor each (category) of the total load The electricity consumption information of electrical equipment realizes (almost) real-time tracking and monitoring, and obtains sub-item electricity consumption information. This technology breaks through the current situation that smart meters can only monitor the total electricity consumption of electric loads. Go deep and refine into the interior of the load. Compared with traditional intrusive monitoring technology, non-intrusive power load monitoring technology has incomparable advantages in investment, deployment and...
