Abstract

The invention discloses an energy online monitoring method, device and system. The method comprises the steps: carrying out the communication with designated equipment in a to-be-monitored system in apreset communication mode, and acquiring the real-time monitoring data of the to-be-monitored system, wherein the real-time monitoring data comprises real-time power generation data, real-time powergrid power supply data and real-time power utilization data; and judging whether the first converter in the to-be-monitored system is in energy balance and/or whether the direct-current bus is in energy balance according to the real-time monitoring data so as to realize energy monitoring according to a judgment result. According to the invention, the real-time monitoring data capable of reflectingthe power generation, power grid power supply and power consumption conditions of the to-be-monitored system is obtained from the specified equipment in the to-be-monitored system in the preset communication mode; the energy balance of the first converter and/or the DC bus is verified based on the real-time monitoring data, so that the comprehensiveness and accuracy of the monitoring data are ensured, the energy flow condition of the new energy system is comprehensively and accurately monitored, and the evaluation and energy management scheduling of the new energy system are facilitated.

Description

technical field [0001] The present invention relates to the field of new energy technology, in particular to an energy online monitoring method, device and system. Background technique [0002] With the research on new energy sources, more and more equipment or systems use new energy sources such as photovoltaics and wind power to generate electricity and provide energy. At the same time, people are paying more and more attention to the improvement of energy efficiency brought about by new energy direct drive technology and the intuitive display of new energy operating status. [0003] The traditional meter billing method cannot be applied to the distributed new energy system, and it cannot realize comprehensive monitoring, nor can it reflect the power generation and electricity consumption of the new energy system. [0004] Aiming at the problem that the new energy system in the prior art cannot be fully and accurately monitored, no effective solution has been proposed yet...
