In this paper we present a switched-capacitor matched filter for the satellite On-Board Data Handling (OBDH) Litton Coded bus. The proposed filter represents the analog frontend of the bus interface (modem) in the Central Data Management Unit (CDMU) and in each Remote Terminal Unit (RTU) of the satellite on-board communication system. The filter consists of a 16-taps switched-capacitor FIR stru...

Nowadays SCADA (Supervisory Control and Data Acquisition) systems became widely used technology. This fact is directly related to the ubiquity of smart systems using a wide range of technologies in control and supervision applications. MCU technology are a very promising technology in this field especially, with the emergence of safety critical MCU, cost/power reduction and wireless connectivit...

In today's competitive electric market, utilities are expected to provide highly reliable power supplies at the lowest possible cost. Distribution automation and remote control are recognized as ways for intelligently using appropriate technology to increase the reliability at reduced system operation cost, automated operations and service restoration can eliminate the need to send out the pers...

The international standard MMS (Manufacturing Message Specification) is an OSI application layer messaging protocol origionally designed for the remote control and monitoring of devices such as Remote Terminal Units (RTU), Programmable Logic Controllers (PLC), Numerical Controllers (NC), or Robot Controllers (RC). It provides a set of services allowing the remote manipulation of variables, prog...

Abstract Internet of Things (IoT) has recently become one the fast‐growing technologies in world. Integrating existing systems with smart grids still represents a significant challenge arising from massive cost upgrading infrastructure. This paper provides an IoT infrastructure solution based on newly designed low‐cost microcontroller‐based remote terminal unit (RTU) to integrate new, old, and ...

In India Power system monitoring is based mainly on measurements provided by Remote Terminal Unit (RTU). For power system measurement synchronized Phasor or Phasor Measurement Unit (PMU) is popular choice in abroad and its popularity is increasing day by day because of its several features. Direct measurement of voltage or current Phasor is possible because of PMU which was not possible earlier...

Supervisory Control And Data Acquisition (SCADA) systems have been widely used in industry applications. Due to their application specific nature, most SCADA systems are heavily tailored to their specific applications. For example, a remote terminal unit (RTU) that monitors and controls a production well in an oilfield is only connected with a few sensors at the well it resides. The RTU usually...

The communication infrastructure of the modern Supervisory, Control and Data Acquisition (SCADA) system continues to enlarge, as hybrid High Voltage Direct Current (HVDC)/Alternating (AC) networks emerge. A centralized SCADA faces challenges meet time requirements two different power topologies, such employing toolboxes for both grids. This paper presents a HVDC/AC network. In addition, case st...

SCADA is designed to automate various systems like process industry, power grid etc. SCADA consist of master station (MS) and a number of remote terminal units (RTU). RTUs are connected to Master Station via communication channels. Communication channel limits the speed of data acquisition and control. To send many data from RTUs to Master Station multiplexing technique like Orthogonal Frequenc...
