Electricy Losses Management in Distribution Network as a Composition of Automated Meter Reading and Control System (AMRCS)

The problem of electricity losses management in distribution electric networks (DEN) operating in conditions of asymmetry of currents and voltages is reviewed. As it is known, the asymmetry factor leads to significant losses of active power and, as a result, decreases the efficiency and technical and economic indicators of the DEN. The purpose of the control is to minimize technical energy losses in the distribution network based on the creation of an automatic control system (ACS) for the process of balancing a three-phase network in the composition of automated meter reading and control system (AMRCS). The latter are currently being widely implemented to automate information processes in DEN. However, AMRCS does not include in its composition technologies designed to solve the problem under review. A method is proposed for constructing a digital ACS controller, the main function of which is to maintain phase currents at the network input at a given level in real time. The concept of the method is based on the idea of the desired redistribution of electricity flows between the phases of the distribution network by appropriate switching of single-phase consumers (customers) so that the minimum spread of phase currents from their specified level is ensured. To achieve the goal of control, criterion functions are constructed that determine the qualitative indicators of the functioning of the ACS. Algorithms for the functioning of the digital controller and the formation of control actions on the subject have been developed. The latter are a digital code containing data on the coordinates of electricity meters of consumers of a three-phase network to be switched to another phase.

Design and Implementation of Smart Energy Meter System with GSM Module

Automated Meter reading systems are an invaluable technological advancement that can lead to a better standard of living, owing to the fact that metering has become a part and parcel of our mundane lives. It solves many issues of the traditional meter reading system like need for human resources, efficiency, accuracy, delayed work, unavailability of customer during metering visit by employee, etc. Moreover it is more economical and helps to save energy in a more efficient and effective way. Furthermore it has a very notable advantage of having the ability to predict the energy demands of the future, starting from every household to the entire planet. The main objective of the smart energy meter is to not only measure the consumer’s power consumption but also to transmit the readings of the meter to utility office every week/day/hour with the help of GSM module or by uploading it onto the cloud. Readings of the meter will be taken out using Rs485 Module and will be given to Raspberry pi and transmitted further to utility office with the help of GSM module or by uploading it onto cloud and at the same time consumption in terms of units as well as rupees will be transmitted to consumer which they can access in SMS or application. Electrical power has become indispensable to human survival and progress which leads to the enhancement of the people’s standard of life by the introduction of automation in to energy distribution and management. With the constant development in technology, the need of automated meter reading systems is also increasing.it is basically Raspberry pi based operational system. The technology of e-metering (Electronic Metering) has gone through rapid technological advancements and there is increased demand for a reliable and efficient Automatic Meter Reading (AMR) system.

To the problem of mathematical modelling of the three-phase asymmetrical distribution network

The asymmetrical distribution electric network is considered in the conditions of functioning of the automated meter reading and control system (AMRCS). The problem of identification of its mathematical model in a complex form which comes down to definition of phase shifts of the variables (currents, tension) defining an electric status of three-phase network is formulated. The method of its solution based on the mathematical ratios describing functional communications between state variables and use of algorithms of parameter optimization is offered. The realization of identification procedure of model of a distribution network is enabled with direct use of the basic data obtained on communication channels from subscriber's meters of the electric power. The method can be used for a solution of a number of functional tasks as a part of the AMRCS oriented for diagnostics of statuses of a trunk line and energy losses in a distribution network.

For the construction of subsystem for power line diagnostic states of distribution networks as a part of AMRCS

At present, in order to automate and informative processes in distribution zones (DZ) with a voltage of 0.4 kV, new technologies have found wide application in the form of automated meter reading and control system (AMRCS). However, as part of these information systems, there are no technologies focused on solving diagnostic problems. The report proposes methodological and algorithmic foundations for constructing a subsystem for diagnosing the states of wires of the main lines of DZ. Diagnostic criteria are formulated based on the assessment of the level of their run-out. The research results are aimed at improving the existing AMRCS and increasing the reliability of distribution networks.
