    Co-Authors: Mohd Ruddin Ab Ghani, S. H. Raman, M.a. Mat Hanafiah, Wan Nor Shela Ezwane Wan Jusoh, Wan Ahmas Redhauddin Wan Hassan, Zanariah Jano
    Abstract:

    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.

    Abstract:

    This paper reviewed all the possible interfacing communication protocols for Remote Terminal Unit (RTU). Supervisory Control and Data Acquisition (SCADA) system is a central station that can communicate with other network using the protocol. Fundamentally, the architectures of all networks are based on the seven layers of open system interconnection (OSI) and International Standard Organization (ISO). The objective of designing the protocols is to check the status of all the input and output field devices and send the report according to that status. The corresponding protocol and communication parameters between the connecting devices will be included in designing a complex SCADA system. The available protocols to develop the communication of RTU are Modbus/ASCII, distributed network protocol (DNP3), controller area network (CAN), International Electro-technical Commission (IEC 60870), and transmission control protocol/internet protocol (TCP/IP).

The master of this system is RTU and the slaves are digital and output modules. RTU plays an important role in detecting fault and assigned to serve message immediately in the control room. This system involves the detection of fault connected to the microcontroller (PIC18F77A) and GSM modem. When the fault occurs, the sensor will send the signals to the PIC16F77A. The PIC is programmed to process the data and send the signals to the GSM modem. Once received the data, GSM will send the message to the control room operators or other authorized personnel to alert them on the current situation through cellular phone. The results are then communicated between hardware circuit and simulation circuit for the final conclusion with the properly functional algorithm.

  • A PC based state estimator interfaced with a Remote Terminal Unit placement algorithm
    IEEE Transactions on Power Systems, 2001
    Co-Authors: Mounir Yehia, Rabih Jabr, Ibrahim Bitar, Rafat Al-waked
    Abstract:

    In this paper a new Remote Terminal Unit (RTU) placement algorithm is presented. The objective of this algorithm is to place a minimum set of RTUs which satisfies three important constraints of the problem-observability, absence of critical measurements, and reliability requirements defined in terms of RTU loss. The problem is solved in a single stage. The results of this algorithm are interfaced with a linear programming (LP) state estimator. This estimator only uses the voltage measurements, and the active and reactive power flows in the lines for the development of the coupled state-estimation Jacobian H-matrix. The injection measurements are not currently included, though in practice they can be easily added to the estimator model. The inclusion of the injection measurements will enlarge the use of the presented algorithm. The RTU placement algorithm and its link with the LP estimator are tested on IEEE standard bus systems. Using the proposed RTU set, the test results presented show that the LP estimator has very good filtering capabilities when operated with or without bad data, and that the loss of any RTU does not have any significant impact on the solution
