Enhance Efficiency

Remote Terminal Unit (RTU) is a standalone data acquisition and control unit which monitors and controls an equipment at a remote location from the central station that utilizes Distribution Automation System (DAS). The RTU acquires information such as measured values, signal, meter readings and it transmits command or instruction, sets points, controls variables and monitors function time. In the present Distribution Automation System (DAS), the distribution field of automation allows the utilities to implement a flexible control of distribution system to enhance efficiency, reliability, and quality of electric service. The implementation of distribution automation system is highlighted based on two factors; benefit and area of distribution automation system implementation. The hardware design uses PIC16F877A microcontroller to control all the functions of RTU. The types of fault detected are undervoltage and overcurrent. The design consists of MPLAB software development using C programming and hardware assembly. RTU is also designed to communicate with the Supervisory Control and Data Acquisition (SCADA) system and resulting in RTU’s ability to detect undervoltage and overcurrent fault.

Weight Allocation

Background: The Remote Terminal Units (RTUs) in the Distribution Automation System (DAS) are widely used in the field in recent years. It is lack of sample data in different operation status that makes the RTU maintenance improper. The weight allocation for the monitoring indicators in the health status evaluation needs to be identified efficiently and properly. Methods: A systematic health status assessment indicator system is constructed firstly. Then, a hybrid indicator weight allocation algorithm based on the Attribute Hierarchy Model (AHM) and grey relational degree (GRA) is proposed to identify the elementary item in the weight allocation under small sample condition. The final indicator weight would be dynamically adjusted according to the equilibrium coefficient, which is determined by the indicator condition parameter. Results: The simulation results show that the weight allocation can be effectively and reasonably adjusted according to the indicator value even under small sample condition. Conclusion: The expert experience and objective data laws are combined and used in our proposed dynamic weight allocation method. It can be used to assess the health status of RTU in the electrical power distribution network.
