Problems solved by technology

[0003] In the previous energy storage monitoring system, the processed real-time data transmitted from the grid-connected system was only monitored through the communication port and related communication protocols. Due to the limitations of various conditions, the system can only be monitored macroscopically. , it is impossible to monitor the measurement points from a microscopic point of view. We urgently need to understand the power parameters of the grid-connected system and the grid interface during the charging and discharging process from a microscopic point of view, and control the new energy according to the changes in the monitoring data. Charging and discharging performance of network devices

Abstract

The invention relates to a data collecting and analyzing device for an energy storage system and a collecting and analyzing method thereof. The device collects data of three paths of voltage signals and three paths of current signals of a grid-connected system in a mode of high speed to realize measurement and calculation of parameters such as voltage deviation, frequency deviation, power factors, voltage harmonic, current harmonic, degree of voltage unbalance and the like and estimate for switching time of charging and discharging of the grid-connected system, and the like. Meanwhile, the device can also test and calculate parameters such as direct voltage, direct current, voltage harmonic, current harmonic and the like of the grid-connected system and the interface part of a direct-current battery pack, and the device detects the influence of the grid-connected system for an energy storage battery pack in real time. If necessary, the device can carry out appropriate alarm and system protection.

Description

technical field [0001] The invention relates to the field of measurement control and electronic communication, and in particular to a data collection and analysis device for an energy storage system and a collection and analysis method thereof. Background technique [0002] With the accelerated development of new energy technologies, more and more new energy sources are connected to the power grid. As a bridge connecting the power grid and new energy equipment, the performance of the grid-connected system directly affects the safe operation and safety of the power grid. No, in these new energy devices, the randomness and volatility of power generation will also affect the power quality of the grid. [0003] In the previous energy storage monitoring system, the processed real-time data transmitted from the grid-connected system was only monitored through the communication port and related communication protocols. Due to the limitations of various conditions, the system can on...
