Abstract

The design of a temperature monitoring and stabilization system on a microcontroller based cold region outdoor jacket by utilizing microcontroller technology, by ensuring user comfort while in a cold temperature environment. This research is shown specifically in cold areas, with the aim of preventing hypothermia commonly experienced by climbers or humans, who are active in cold areas. The results of the system research on outdoor jackets that can monitor and stabilize the user's body temperature automatically, especially in cold areas. This system uses an ESP32 microcontroller, which is equipped with the Blynk application to control and monitor temperature using a smartphone. When the ambient temperature drops below 20°C, the system automatically activates the carbon fiber heating pad to maintain a stable body temperature. The jacket is designed to function offline, where the system will rely on the temperature sensor to activate the carbon fibre heating pad if the temperature drops below 20°C. Test results show that the system works well, providing efficient results in power consumption, responsive to temperature changes, and effective in maintaining temperature stability. The resulting jacket is comfortable and safe so that it does not interfere with outdoor jacket users in various conditions.

Abstract

Frequency stability is a key indicator of power system reliability, as disturbances such as generation loss can cause rapid frequency decline and potentially lead to a blackout. This study evaluates the effectiveness of a load shedding scheme using an Under Frequency Relay (UFR) at the Arun Substation through dynamic simulation in DIgSILENT PowerFactory. The scenario involves a sudden loss of generation, comparing conditions without and with UFR. Results show that without UFR, a 48.421 MW power loss causes the frequency to drop below 42 Hz in less than 16 seconds, leading to system failure. With a two-stage UFR scheme (27.6 MW at 49.5 Hz and 28.4 MW at 49.2 Hz), the frequency decline is arrested and the system stabilizes at 50.12 Hz within about 3 seconds. Thus, the UFR scheme is effective in maintaining system stability.
