Abstract

With a range of long distances or depths and areas beyond the reach of the internet it is necessary to design a wireless SCADA system based on the AX.25 protocol for the purpose of monitoring Micro hydro power generation and forming a prototype in a model of a micro hydro power plants (Micro hydro power plant) wirelessly monitoring system. The method used in this research is quantitative method, by designing a system to monitor Micro hydro power plant wirelessly by utilizing AX.25 protocol. This system can monitor several Micro hydro power plant parameters such as voltage, current and frequency and turbine rotation so that it can be accessed directly at one central location. Data transmitted by Remote Terminal Units (RTUs) may serve as a reference for operators to decide on further steps if any monitored Micro hydro power plant parameters change from a predetermined standard. This prototype has been simulated using the Proteus 8.6 and LabView 2012 software. Data from the sensors transmitted over radio frequency using KYL 1020 from each RTU to MTU and connected to the computer using LabView software and displayed on the computer with taking into account the operating parameters, characteristics and workings of the AX protocol. The RTU system has been successfully simulated using 2 ACS712 current sensors, voltage sensor, zero crossing point, frequency sensor and rotation sensor functional for monitoring Micro hydro power plant parameters. The AX.25 protocol has been applicable in the wireless SCADA network for monitoring the performance of the Micro hydro power plant by embedding in a KYL-1020UA transceiver radio using the 433 MHz frequency and the AFSK modulation system. Radio transmitter KYL-1020UA has been successfully simulated to send data from sensors to display on the computer through SCADA built applications.

Abstract

The trend of converting direct current (DC) system into alternating current (AC) using inverter becomes common since the system efficiency appropriately improves. Additionally, the mitigation on direct-DC power system requires transformer and inverters inside the appliances due to lower and convert the 230VAC into useable DC voltage. This paper proposes the direct-DC power system generation based on single-phase rooftop photovoltaic (PV) in the residential low voltage (LV) feeder. The proposed simulation designates the power system components included in the modeling of the AC and direct-DC houses, which the included power system components downstream of the PV array. The efficiency of direct-DC power supply, grid interactive inverter and charge controller are simulated. The results show that the peak curve efficiency of direct-DC power supply has DC power input narrow to 400VDC. It is then become 2% higher than 220VAC power input. While the inverter with multiple MPPT efficiency curve has the peak of 96-97% after 30% loads, while when it is partly loads, with the power capacity below 1000W, has peak at range of 86-95%. Then the efficiency curve of charge controller with MPPT for partly load scheme below 30W output power the peak is about 90-94%.
