Abstract-
Due to the rapid development in automation system, control and monitoring are necessary for any modern
system. DCS provides this control and monitoring for industrial automation. The system is designed and constructed
Distributed Control System (DCS) based power distribution in university campus. The research has constructed
hardware and utilized Microsoft Visual Basic software in software environment using a communication network and
embedded controllers. All hardware and software components have been developed and integrated together. Data
exchange mechanism, USB cable has been developed between the host computer and the embedded controllers that
function in two way data exchanges between the two. This system uses PIC 18F4550 microcontroller to collect electrical
parameters of devices in each departments. The Graphical User Interface (GUI) uses Visual Basic Software under
Microsoft Visual Basic 2010 express to achieve data real-time display and status display for the loads.

NTRODUCTION
Power distribution DCS is a computer based production process control and monitoring system. It uses the data
acquisition module to monitor and control the operation of field devices so as to achieve data acquisition, device
control. The power distribution DCS system has many advantages, such as information integrity, efficiency, correct
grasp of system running status, speeding up decision-making, and can help quickly detect the failure state of the
system. It has become an essential tool for power dispatching [1]. For power control and monitoring, many wire and
wireless technologies are discussed. These are GSM, zigbee, SCADA, DCS and Microcontroller. In [2], [3] and [4],
power monitoring module calculates power consumption for home appliances. Zigbee communication module is
used to send measured data of current and voltage to server module and store it in computer. Authors design the
GUI by using Visual Basic (VB) to provide user friendly environment.
The main aim of this paper is to design and construct a low cost controlling wired system between server and
clients for power distribution in university campus using microcontroller. In this paper, power control and
monitoring is designed by using DCS. DCS is suitable for power monitoring and control because it can control in
various control system. This design mainly uses visual basic software to conduct configuration design for the power
distribution monitoring system. By using DCS, the distribution system is made more secure, reliable and efficient
because it is widely used for modern power system and more popular than any other control system [5]. DCS refers
to a control system that available in manufacturing system, process or any kind of dynamic system, in which the
controller elements are not central in location (like the brain) but are distributed throughout the system with each
component sub-system controlled by one or more controllers. The entire systems of controllers are connected by
networks for communication and monitoring. DCS is a very broad term used in a variety of industries, to monitor
and control distributed equipment. DCS is connected to sensors and actuators to control the flow of materials
through the plant [6]. The architecture of the DCS is shown in Figure 1.
