This project is titled design and construction of wireless load controller by GSM. Wireless load controller by GSM is an electronics gadget designed to automatically regulate and controls the rotational speed of a hydro electric generator system by adding or deducting an array of dummy loads which is to be controlled and monitored with GSM. The procedure ensures a stabilized voltage and frequency output for the user using handset.
This project consists of a micro-controller P89C51RD2 or 8051 , KEYPAD and Motors, The motors are interfaced with each other forming an arm of a robot which are further interfaced to a keypad, The total setup is interfaced to a micro-controller which consists of operating instructions (codes), these are the instructions used to control the motion of the motors in forward and backward directions in steps, this instructions are written in a specific coding language which are constructed using a developing tool.
The aim of this project is to design & develop the wireless load controller by the GSM. GSM controller is a low cost solution to Remote Control and Monitoring via your mobile phone. It has 2 relay outputs and 4 contact closure inputs. Outputs can be used to control lighting, central heating boiler, pumps etc and the inputs can be connected to thermostats, security sensors and flood detectors.

 

 

CHAPTER ONE

• INTRODUCTION

If you are one of those lucky people who have a free flowing creek, river stream or even an active small water fall near your backyard, you can very well think of converting it into free electricity simply by installing a mini hydro generator in path of the water flow, and access free electricity for lifetime.

However the main problem with such systems is the speed of the generator which directly affects its voltage and frequency specs. Here, the rotational speed of the generator depends on two factors, the power of the water flow and the load connected with the generator. If any of these alter, the speed of the generator too alters causing an equivalent decrease or increase in its output voltage and frequency.
As we all know that for many appliances are such as refrigerators, ACs, motors, drill machines, etc voltage and frequency can be crucial and may be directly related to their efficiency, thus any change in these parameters cannot be taken lightly.
In order to tackle the above situation so that the voltage and the frequency both are maintained within tolerable limits, an electronic load controller is normally employed with all hydro power systems.
Since controlling water flow cannot be a feasible option, controlling load in a calculated manner becomes the only way out for the above discussed issue.

This is in fact rather straightforward, it’s all about employing a circuit which monitors the voltage of the generator and switches ON or OFF a few dummy loads which in turn control and compensate for the increase or decrease in the speed of the generator.

• BACKGROUND OF THE PROJECT

The  project  aims  at  designing  a wireless load controller by GSM which   can   automatically regulate and controls the rotational speed of a hydro electric generator system by adding or deducting an array of dummy loads which is to be controlled and monitored with GSM. The procedure ensures a stabilized voltage and frequency output for the user using handset.
This project consists of a micro-controller P89C51RD2, KEYPAD and Motors, The motors are interfaced with each other forming an arm of a robot which are further interfaced to a keypad, The total setup is interfaced to a micro-controller which consists of operating instructions (codes), these are the instructions used to control the motion of the motors in forward and backward directions in steps, this instructions are written in a specific coding language which are constructed using a developing tool.

1.3                                         OBJECTIVE OF THE PROJECT
The main objectives of the project are to monitor and control the speed of hydro generator thereby controlling the load using GSM.

1.4                                       SIGNIFICANCE OF THE PROJECT
The project provides the following learning’s:

• GSM Control Unit using SMS text messaging
• 2 x mains rated relay outputs for switching for example lights, pumps, central heating
• 4 x contact closure inputs from example PIR detectors, flood detectors, security alarm systems etc
• Can switch on/off outputs from simple SMS text message
• Can send an SMS message when a input changes state
• Uses standard mobile phone SIM card, including pre-paid
• Easy to use and configure via SMS, the internet or optional USB lead
• Optional battery back-up for operation even during mains power failure
• Optional wireless sensor interface for use with;
• Wireless thermostat for heating control
• Wireless Fire and Smoke detectors
• Wireless PIR and Glass break Security sensor
• Wireless remote switch output unit

1.5                                              BENEFITS OF THE PROJECT
In power generating, when the load on a system approaches the maximum generating capacity, network operators must either find additional supplies of energy or find ways to curtail the load, hence load management. If they are unsuccessful, the system will become unstable and blackouts can occur – which affects mankind. In other to address this problem a wireless load controller is used, which control the speed of hydro-generator by using GSM

 

1.6        AREA OF INVESTIGATION AND PROGRAMMING LANGUAGE

• Micro controller
• Max 232 circuit
• Wireless transceiver module
• GSM modem

1.7                                               PROBLEM STATEMENT
One of the limitations about this is non availability of power because the power system makes use of power supply from Power Holding Company of Nigeria (PHCN). Though this is a major problem but with thought about alternative source of power, it is a problem that will soon be a by-gone. Also another limitation noticed in the above work is the failure of network or busy network which will make the phone embedded in the system not to be available when called.
Another problem was, of course, maintenance and wear. Mechanical systems need to be lubricated, cleaned, adjusted, and even then they break down rather easily. Specially the mechanical brake system produced a lot of friction, heat and wear. Add to this an assortment of problems like the tendency of spear valves to clog with small debris, and the tremendous spray in the turbine housing when a deflector is used.  

1.8                          PROJECT WORK ORGANISATION
The various stages involved in the development of this project have been properly put into five chapters to enhance comprehensive and concise reading. In this project thesis, the project is organized sequentially as follows:
Chapter one of this work is on the introduction to wireless load controller via gsm. In this chapter, the background, significance, objective limitation and problem of wireless load controller via gsm were discussed.
