Abstract

This paper proposes a cheap solution to be a starting point for building smart electrical power billing systems. Electrical power has many challenges issues in Iraq, one of these challenges and the most important is the Billing system. The smart power meter uses an Arduino Uno as the core for controlling the sensed data and transmits it to the electrical power unit for billing services. The system is constructed with two parts: the transmitting unit measures the current, voltage, power and power factor through the compact new sensor PZEM-004T. The data sensed and processed by the microcontroller which displayed the KWh on (2*16 LCD) display. This data also transmitted to the electrical power company unit via the global system for mobile communications (GSM) module (SIM900A) which is a dual band GSM/GPRS-general packet radio service modem. The receiving part is mainly dedicated for collecting the required consumed power data via the same (SIM900A) module and also can display it using (2*16 LCD) display. For the sake of saving these data, the receiver part uses SD ram for such purposes. With such proposed system the electrical power company can control and collect their fees monthly without loss and with minimum cost.

Abstract

In recent years, the demand for energy generated by photovoltaics has increased because of the cheapness of this energy, especially in the Middle East. This study focuses on the design and implementation of a three-phase photovoltaic inverter system for distribution of generator applications. The three-phase inverter used in this study was designed using GWM 100-01X1 as a three-phase full bridge MOSFET package. The MOSFET full bridge of the three-phase inverter is driven using IR2104 gate driver IC, and the Hall sensors of the voltage and current are used to measure the AC and DC voltage and current. The SPWM signal is generated using a PIC24FJ256GB110 as a microcontroller and interfaced to the full bridge package. Simulation and experimental results are presented to validate the three-phase inverter design.
