ABSTRACT: Voltage and frequency are usually considered and assessed independently
in the design and operation of electrical networks. However, these two are
linked. Each and every malfunctioning electrical system has an impact on both
voltage and frequency. This paper presents the opportunity for monitoring the
distributed electrical energy by means of a system that monitors, controls, and
provides a breakpoint based on high or low voltage and frequency tripping
mechanism that avoids any damage to the load. The designed system comprised a
switch mode power supply (SMPS), a direct digital synthesizer (DDS), and
PIC16F876A microcontroller techniques for stable voltage and frequency outputs.
Proteus design suite version 8.11 software and Benchcope SDS1102CN were used
for modeling and simulation. The hardware prototype was implemented at a
telecom cell site for data capturing and analysis. Test results showed that the
implementation of the prototype provided stable and constant outputs of 222
V/50 Hz and 112 V/60 Hz which constituted 99% and 99.8% efficiency for voltage
and frequency performance respectively. The paper also discusses different
technologies that can be adopted by the system to mitigate voltage and
frequency effects on customer appliances.
