IRJET- Wireless Data Monitoring and Fault Identification by using IoT in Thermal Power Plant
0 likes84 views
This document describes a wireless IoT-based system for monitoring key parameters like temperature, vibration, pressure, and level in a thermal power plant. The system uses sensors to monitor these parameters, an Arduino microcontroller to process the sensor data, and an IoT module to transmit the data remotely via SMS. This allows plant operators to continuously monitor the parameters anywhere, increasing reliability while reducing maintenance and operating costs compared to manual monitoring. If any parameter exceeds a threshold, workers are alerted to potential issues via on-site displays and remote notifications, allowing faults to be identified early.

Aarthi1, R.Mohanapriya2 , G.Siva3, K.Arun4, G. Balaji5 Department of Electrical and Electronics Engineering Knowledge Institute of Technology --------------------------------------------------------------------------*****-------------------------------------------------------------------- Abstract: Thermal Power Plant has to operate regularly. It is difficult to monitor the parameters at each and every moment manually. In order to increase the reliability of thermal power plant, then to reduce maintenance and operating cost, remote monitoring is necessary. This paper develops IoT based monitoring system. It consists of Temperature, Vibration, Pressure and Level sensor. These sensor’s data are processed by ATmega 328 controller which is transmitted through IoT module to remote place. It provides current updates through SMS anywhere in the plant and outside of the plant. Keywords : AT mega 328 controller, IOT module, Monitoring system, Reliability, Operating Cost, Sensors 1. INTRODUCTION In Thermal Power Plant, It is necessary to monitor parameters like Temperature, Pressure, Level, and vibration because the equipment like Boiler, Turbine are affected by this parameters. If any of these blades in turbine gets damaged , it create unbalanced condition so that vibration level gets increased. If vibration level increases, it causes desirabledamagestosystem. If percentage of the steam flow is increased, the pressure of the steam is also increased. So that it rotates the turbine at high speed. Because of the high speed, it causes damage to turbine blades. If level of the steam is increased, the pressure in the boiler tube increase. If Presssure in the drum in the increases, the drum get blast. If temperature increases above the specified value, it leads to damage to the system. This paper mainly concentrate on how to monitor the temperature, vibration, level and pressure in boiler and turbine. 2. COMPONENTS 2.1. Arduino UNO The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet).Ithas14digital input/output pins(ofwhich 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. Arduino Uno can be powered via the USB connection or with anexternal powersupply.Thepowersourceis selected automatically. External (nonUSB) power can come either from an AC to- DC adapter (wall -wart) or battery. The adapter can beconnectedby plugging a 2.1mm center -positive plug into the board's power jack. Leads froma batterycanbe insertedintheGndandVinpin headers of the POWER connector. The board can operate on an external supply of 6 to 20 volts. If supplied with less than 7V, however, the5Vpinmay supplyless than five volts and the board may be unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts.

Input Voltage is 7-12V. Input Voltage is 6-20V. Digital I/O Pins is 14. Analog Input Pins is 6. DCCurrent per I/O Pin is 40 mA. DC Current for 3.3V Pin is 50 mA. Flash Memory is 32 KB of which 0.5 KB used by boot loader. SRAM is 2 KB (ATmega328). EEPROM is 1 KB (ATmega328). 2.2. Relay A relay is an electrically operated switch. Current flowing through the coil of the relay creates a magneticfieldwhich attractsa lever and changes the switch contacts. The coil current can be on or off so relays have two switch positions and most have double throw (changeover) switch contacts. Relays allow one circuit to switch a second circuit which can be completely separate from the first. For example a low voltage battery circuit can use a relay to switch a 230V AC mains circuit. There is no electrical connection inside the relay between the two circuits, the link is magnetic and mechanical. The coil ofa relaypassesa relatively large current, typically 30mA for a 12V relay. 2.3. IOT module NodeMCU is an open source IoT platform. It includes firmware which runs on the ESP8266 Wi-Fi SoC (System on Chip) from Espressif Systems, and hardware which is based on the ESP-12 module. The term"NodeMCU" bydefaultreferstothefirmware rather than the development kits. The firmware uses the Lua scripting language.Itis basedontheeLua project,andbuiltonthe Espressif Non-OS SDK for ESP8266. It uses many open source projects, such as lua-cjson,and spiffs. Specifications: 802.11 b / g / n wireless standards, STA / AP modes support, TCP / IP protocol stack,Onesocket,Supportsstandard TCP/ UDP Server and Client. Temperature is between -40℃ ~ + 125℃. Humidity is 10%-90% non-condensing. Weight is about 20g (0.7oz).

Dependinguponthetemperaturetobe measured,therequired accuracyof the measurement, and other factors such as durability , the type of sensor to be chosen In this paper using NTC thermistor as a temperature sens233weor. NTC thermistor is a precision IC temperature sensorwith its output. The sensor circuitry is sealed and therefore it is not subjected to oxidation and other processes. With NTC thermistor, temperature can be measured more accurately than other types of sensor. It also possesses low self-heating. 2.5. Pressure sensor Pressure sensor is uses to measure the pressure in the steam. It measures the amount the amount of force applied on a unit area. There are different types of pressure sensors are available for power plant operation. In this paper use KRD532C High Precision Digital Pressure Sensor Board Module. . 2.6. Level sensor It is used to determine the liquid level which flows in an open or closed system. The level measurementscanbepossibleintwo types namely continuous measurements and point level measurements. The continuous level sensor measures level within a specified range and give exact results. Point level sensors is used to determine the amount of liquid substances whether it is low or high.
