Principles of construction of a multifunctional intelligent electric energy meter with advanced communication and functional capabilities

Abstract

Objective. Development of principles for the construction of a multifunctional intelligent electric energy meter (MSE) with expanded communication and functional capabilities and the construction of MSE based on them for automated systems of commercial accounting of energy consumption (ASKUE).Method. When developing the principles of the construction of the IEE, an analysis of existing electric energy metering devices was carried out and their main disadvantages were identified, which made it possible to improve the characteristics and expand the functionality of metering devices. The operability of the main components of the IEE is confirmed by the results of mathematical and physical modeling, which showed the possibility of improving the metrological characteristics and technical parameters that determine the quantitative, qualitative and cost characteristics of the devices.Result. The principles of the construction of the IEE have been developed, which makes it possible to create IEE with expanded communication and functional capabilities for the ASUE.Conclusion. Using them in ASCUE posvolit: -to build self-adjusting mesh networks based on them, which can be used in the construction of ASCS with increased survivability; -to ensure the exchange of accounting and service information with the ASKUE over the radio channel, PCL modem and RS-485 (CAN) interface, which increases the reliability of obtaining accounting information and integrate the MISEE into existing ASKUE, because it makes it possible to select the appropriate type of specific ASKUE interface or communication interfaces "counter-ASKUE";- regulate energy consumption and independent disconnection of the consumer from the network for each subscriber unit (separately for each subscriber) in case of arrears of payments, network overload and unauthorized access to the nodes and blocks of the meter in various ways;- to improve the operating conditions of the meter when organizing electronic payments and increasing the reliability of accounting information due to contactless remote removal of information by means of communication interfaces for each subscriber or by means of an individual remote control (remote control).-to reduce the hardware costs of servicing one subscriber associated with the use of the main units and units of the meter to account for energy consumption for all subscribers, and, as a result, the low cost of electricity metering in recalculation per subscriber.
