ENCS-3m, manual. 403500.001 Rev. 3.2016 4 General information 1 General information ENCS-3m - is a reliable software and hardware platform for building remote control sys- tems for substation and power plants. Remote terminal unit (RTU) ENCS-3m is designed to create geographically distributed systems: — at the field level installed devices (ENIP-2, ENB series) which support measurement parameters values, monitoring digital signals and control by digital outputs to switch- gears and mechanism; — all this devices are connected to RTU ENCS-3m via RS-485/232 lines or local net- works. RTU ENCS-3m collect, consolidate and distribute necessary data to a top level of con- trol systems. To control data traffic from field level devices ENCS-3m uses absolute and relative apertures. Timestamps of data are assigned by field devices. ENCS-3m build on 32bit ARM microcontroller and providing continuous operation for remote control systems. To increase reliability system ENCS-3m support warm standby. ENCS-3m use hard real-time algorithm, and thus provides high performance and relia- bility. ENCS-3m polls devices according IEC 60870-5-101, Modbus and etc. ENCS-3m support up to 10 ports for device polling. ENCS-3m allows setup up to 16 channels to transmit data to upper level using 2 LAN and RS-232/RS485 ports. 2 RTUs ENCS-3m are connected through CAN-bus to support warm standby in pair. RS-485 interface, RS-232, Ethernet can be distributed by the user between data collec- tion from field devices and transmission of information to the top level. To communicate with the field devices are preferred protocol IEC 60870-5-101, which provides for the regulation of traffic between the RTU and devices, and allows to send a data with timestamp directly from the sources of their formation.

The resulting filtered data is stored in RAM and are available for the rest of the program RTU modules. Starting polling performed on all ports in a one time. Thus, all the data obtained from the field level devices have the same meanings recorded for a time If the device has an internal clock, ENCS-3m provides time synchronization within the IEC 60870-101 protocol, as well as through the proprietary protocol for some meters. 3.2 Telecontrol ENCS-3m can transmit command according to IEC 60870-5-101 (Single command (<45>), Double command (<46>)) and Modbus (Force single coil (05). For Modbus you can choose type of retranslation Single command (<45>) from top level to Modbus command (05) for field level device. 3.3 Spontaneous transmission Spontaneous transmission mode involves the transfer option under certain conditions: change the value of the parameter is outside the redistributions predetermined value (setpoint or aperture). The value of tolerance can be set both in absolute and relative terms (as a percentage of the current value). Also two setpoints can be specified, at the intersection where the parameter is queued for transmission. This algorithm mode is used to control the voltage when it is necessary to pass a parameter at the exit of some of its frame. 3.4 Cyclic transmission The RTU may transmit parameters to the top level at predetermined intervals (default 2 min.). 3.5 Background scan Background scan has lowest priority for transmitting and start only when data buffer according to IEC 60870-5-101–2006 (IEC 60870-5-104–2004) is empty. 3.6 IEC 60870-5-101–2006 and IEC 60870-5-104-2004 support Available commands: ENCS-3m, manual. 403500.001 Rev. 3.2016 8 Features <45> - single command; <46> - double command; <100> - interrogation command; <101> - counter interrogation command; <103> - clock synchronization command.

  • Remote Terminal Unit (RTU)
    Eaton Smart Grid solutions for Ring Main Units Remote Terminal Unit (RTU) The Remote Terminal Unit is a device for acquiring, processing, storing and transmitting information Measurement and control on the medium voltage (MV) and transformer side of a Ring Main Unit (RMU) will reduce the outage time and the possibility of outages. In more advanced applications with directional fault indicators and some logic, outages can be solved within seconds after a fault has occurred. After an anomaly has been detected, the RMU will automatically contact the operating center where the information is shown on a SCADA system and where actions can be taken to solve or prevent problems. A RTU can also measure Current and Voltage at the low voltage (LV) side of the RMU. By comparing these figures with the information from smart meters, deviations can be detected easily which indicates either a fault or an illegal power tap. Benefits of using RTU for Utilities Nowadays, utility companies are mainly looking for automated Eaton developed this Remote Terminal Unit (RTU) medium voltage solutions due to the focus of these two goals: especially focusing on Ring Main Units applications • Improve standard IEEE reliability indices: for the medium voltage grid. n SAIDI: System Average Interruption Duration Index (SAIDI) The RTU enables utilities to reduce the duration of power n SAIFI: System Average Interruption Frequency Index (SAIFI) outages.

Credit Seminar Report, Electronics Systems Group, EE Dept, IIT Bombay, submitted November 03 Comparison of protocols used in remote monitoring: DNP 3.0, IEC 870-5-101 & Modbus Jay Makhija (03307905) Supervisor: Prof. L.R.Subramanyan Abstract A brief introduction to IEC 870-5-101, DNP 3.0 and Modbus is presented together with the explanation of functionalities provided by these protocols. Comparison between these protocols, considering various aspects like architecture, functions performed by individual layers, device addressing and configuration parameter s etc is done. Here objective is to compare protocols not to conclude which one is better. Selection of protocol depends mainly on application, specific requirements and functions to be carried out, which protocol to be used for what purpose is discussed. 1. Introduction In a SCADA system, the RTU accepts commands to operate control points, set analog output levels, and provide responses, it sends status, analog, and accumulator data to the SCADA master station. The data representations sent are not identified in any fashion other than by absolute addressing. The addressing is designed to correlate with a database contained in the SCADA master station, and the RTU has no knowledge of which unique parameters it is monitoring in the real world. It simply monitors certain points and stores the information in a local addressing scheme. Figure 1 illustrates the data and control flow between a master station and one or more RTUs.

Abstract: The communication infrastructure of the modern Supervisory, Control and Data Acquisition (SCADA) system continues to enlarge, as hybrid High Voltage Direct Current (HVDC)/Alternating Current (AC) networks emerge. A centralized SCADA faces challenges to meet the time requirements of the two different power networks topologies, such as employing the SCADA toolboxes for both grids. This paper presents the modern communication infrastructure and the time requirements of a centralized SCADA for hybrid HVDC/AC network. In addition, a case study of a complete cycle for a unified Weighted Least Squares (WLS) state estimation is tested on a hybrid HVDC/AC transmission network, based on Voltage Source Converter (VSC). The cycle estimates the elapsed times from the sensors up to the SCADA side, including the data acquisition and the WLS processing times. The case study is carried out on the Cigre B4 DC test case network with 43 virtual Remote Terminal Unit (RTU)s installed and 10 data concentrators, all connected through a fiber-based communication network. It is concluded that the time requirements can be fulfilled for a hybrid HVDC/AC network.
