Project Summary

There are two main concepts that are proposed in this project i.e. net metering using green energy and data analysis of appliances to introduce the idea of reactive power tariff in the electricity bill due to usage of high inductive and non-standard appliances. We design master ad slave meter in which master meter can be used for bi directional net energy metering so that we know how many energy consumed from either side of meter but slave meter can be used for data analysis of load and find power quality using harmonics.

Project Objectives

The objective is to design a device that monitors power quality parameters of any connected appliance to introduce tariff for reactive energy consumed to minimize the use of non-standardize appliances and energy wastage.

Secondly move towards green energy utilization using solar instead of non-renewable energy resources.

Project Implementation Method

In the master node which is bidirectional meter, we measured the voltages and currents at the both ends of the sources. These values send to the microcontroller and then we calculate the active and reactive power of the load. Also tells the direction of the current which can be drawn by the load.

In the slave node, we measured the voltage and current.The values send to the microcontroller and then we calculate the active and reactive power of the load.Also data analysis of harmonics of connected load. Also the communication of master node to slave node.

Benefits of the Project

• Net metering allows customers to generate their own electricity in order to offset their electricity usage. If more electrical energy is produced from the system(renewable energy source) than the customer needs then additional kilowatt-hours are measured, fed into the utility’s electric system and utilized by other customers
• Energy price can be reduced by producing own cheap electrical energy
• It is environmental friendly
• We know about quality due to different loads which produces harmonics

Technical Details of Final Deliverable

The main aim of this project is to measure current,voltage and power flow direction so this can be achieved by using below mentioned method.

• Current sensing can be done by shunt resistors (50W) in series with load and voltage drop across resistor used for measuring current which will be input of differential amplifier and then output of amplifier goes to controller.
• Voltage sensing can be done by potential transformer (220V/18V) after wich we give input of differential amplifier through voltage divider across potential transformer and finally output of amplifier goes to controller for further processing data in controller.
• Power flow can identified by using current direction.
• We need DC shift for making signal positive so it needs voltage regulator LM338 which gives adjustable output voltage by making different resistors combination.   
• As DC source required for regulator so we make rectifier circuit (AC-DC) and then used voltage regulators for dual 12V supply.
