Power utilization information acquisition method and power utilization information acquisition device

Abstract

The invention relates to the technical field of power system power utilization information acquisition, provides a power utilization information acquisition method and device, and is applied to a power utilization information acquisition system. The system comprises a main station, an energy controller, a CCO, a plurality of STAs and power utilization information metering equipment corresponding to each STA, wherein the main station, the energy controller, the CCO, the STAs and the power utilization information metering equipment are connected in sequence. The method comprises the following steps: the CCO reads cached power utilization information from the STA according to a received power utilization information reporting instruction, and reports the read cached power utilization information to the main station, wherein the cached power utilization information is obtained by actively reporting the power utilization information metered by the power utilization information metering equipment to the corresponding STA by the power utilization information metering equipment. According to the technical scheme, the transmission efficiency of the power utilization information can be effectively improved so that the adjustment and decision-making capabilities of the main station are improved.

Description

technical field [0001] The invention relates to the technical field of electricity consumption information collection in electric power systems, in particular to an electricity consumption information collection method and a power consumption information collection device. Background technique [0002] The power consumption information collection system is used to collect the power consumption information of users in the power system, so that the main station can realize power consumption monitoring, step pricing, load management, line loss analysis, power consumption inspection (anti-theft) based on the collected power consumption information electricity), load forecasting, and saving electricity costs. [0003] The existing power consumption information collection method is that the master station initiates the collection command actively, and the command passes through the energy controller to the CCO (Central Coordinator, central coordinator), and then to the STA (Statio...

AI Technical Summary

Problems solved by technology

[0004] In the above method, in the process of collecting power consumption information, the master station needs to issue a collection command to read each frame of power consumption information, which makes the operation of the whole collection process cumbersome, the operating frequency of each device is high, and the data transmission efficiency is low.

And due to the limitation of the communication rate of the power system, when the number of users is large or the amount of power consumption information is large, the communication pressure of the entire acquisition system is relatively high, resulting in the master station not being able to obtain the current power consumption information data of each user terminal in time. And then affect the adjustment and decision-making ability of the master station to the system
