Problems solved by technology

[0004] However, household electricity consumption is complex and diverse, with a large power variation range and frequent load fluctuations disturbed by external noise. Based on mature non-intrusive monitoring technology, the existing approximate rectangular metering method and fluctuation metering method cannot reflect the load. The fluctuating nature of power during operation, the power metering is not accurate enough

Embodiment Construction

[0039] Below in conjunction with the appendix of the present invention Figure 1~5 , clearly and completely describe the technical solutions in the embodiments of the present invention, obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0040] refer to figure 1 , a method for classified measurement of electricity consumption based on the complex trapezoidal method includes the following steps:

[0041] S1: At the entrance of the user's power line, the line current and voltage are sampled in real time and the data is recorded, and the power consumption data of a user in a certain period T is obtained. There are L loads in the period T, and the period T is divided into N Divide each sub-period t into n equa...

Abstract

The invention relates to the technical field of power consumption calculating, and aims to provide a power consumption classified calculating method based on a compound trapezoidal method. The methodcomprises following steps of S1, acquiring electric power data in a certain period T of a user, dividing the period T with L load power into N time segments t, dividing each time segment t into n equal time slots, acquiring n piece of sampling data, and performing S2; S2, calculating power of a single load in each time slot, and performing S3; and S3, according to the power of a single load in each time slot, calculating power consumption of a single load in each time segment t by using the compound trapezoidal method, and calculating total power consumption of the load in the period T according to the power consumption of a single load in each time segment t. The method has the advantage of improving calculation accuracy of power consumption.

Description

technical field [0001] The invention relates to the technical field of electricity metering, in particular to a method for classified metering of electricity consumption based on the complex trapezoidal method. Background technique [0002] With the rapid development of my country's economy and the optimization of the industrial structure, the demand for the quantity and quality of electric energy in various industries and household users is increasing day by day. In order to save electric energy, reasonably arrange the electricity consumption plan, alleviate the social energy pressure and realize the sustainable development of energy. , put forward the real-time monitoring of electric energy and electric quantity classification metering. The existing monitoring methods for household load classification and metering mainly include two types: intrusive and non-invasive. The intrusive method installs a meter on each load to be monitored for separate monitoring and measurement....
