The SICAM PAS power automation system provides innovative solutions for the most diverse tasks in spatially distributed information systems. This system is equally suitable for using in the substations of electric utility companies as in industrial plants. SICAM PAS has been designed as a modular, open system, which complies with all widely used communication standards. It supports the operator in the implementation of project-specific tasks in the fields of substation automation and power automation. Multiple functions are detection and evaluation of Power Quality measuring data (PQ measuring data) for checking the network quality complementing the possible fields of application of the SICAM PAS system. The User Administration tool ensures that system configuration, operation and system management tasks can only be performed by authorized persons.
The assignment of individual switching authorities down to the information level further enhances the security of system management. The notification functions notify you by an e-mail and/or SMS on pending network faults, fault records, and reports, for example, fault location reports. The system can be structured redundantly on the system, interface, and device level. This approach significantly improves fail-safe operation. In the case of an interruption of a communication link, the redundant component takes over the process connection. Depending on the transmission protocol, the process image of the redundant system is updated either continually or by means of a general request upon process takeover.
The DNP 3.0i and IEC 60870-5-104 protocols allow TSL-based, secured data transmission via certificates.
In Ethernet TCP/IP networks, switches are used for communication with the terminal equipment. SICAM PAS supports the SNMP protocol (Simple Network Management Protocol) for monitoring the operational status of such components and for speedy error detection in order to ensure operational reliability.
Human Machine Interface (HMI): –
The front panel show and push buttons or a private laptop act as interfaces to system information and controls for personnel within the station. SCADA systems are wont to monitor and management physical processes concerned in business and infrastructure on an outsized scale and over long distances. SIMATIC WinCC is used in HMI system Siemens controllers.
Power System Control: –
Control refers to sending command messages to a tool to work the I&C and power system devices. ancient superordinate management and information acquisition (SCADA) systems think about operators to supervise the system and initiate commands from an operator console on the master pc. Field personnel can even management devices using front-panel push buttons or a laptop personal computer.
Power System Automation: –
System automation is that the act of mechanically dominant the ability system via automatic processes inside computers and intelligent I&C devices. The processes accept information acquisition, facility direction, and facility management all operating along in a very coordinated automatic fashion. The commands are generated mechanically so transmitted within the same fashion as operator initiated commands.
I&C System: –
IEDs I&C devices built using microprocessors area unit normally noted as intelligent electronic devices (IEDs). Microprocessors are single chip computers that permit the devices into that they are built to method information, settle for commands, and communicate data sort of a laptop. Automatic processes are often run within the IEDs, and communications area unit handled through a port just like the communications ports on a laptop. IEDs are found within the substation and on the pole-top.
Remote Terminal Unit, (RTU): –
A remote terminal device, RTU, is an IED which will be put in during a remote location, and acts as a termination purpose for field contacts. an infatuated combine of copper conductors are wont to sense each contact and electrical device price. These conductors originate at the ability system device, are put in in trenches or overhead cable trays, and area unit then terminated on panels at intervals the RTU. The RTU will transfer collected data to alternative devices and receive knowledge and management commands from alternative devices through a port. User programmable RTUs are said as “smart RTUs.”
Programmable Logic Controller (PLC): –
As the name implies, a programmable logic controller (PLC), is an IED that may be programmed to perform logical management. like the RTU, an avid combine of copper conductors for every contact and electrical device worth are terminated on panels inside the PLC. Personnel familiar with the PLC development surroundings will program PLCs to make info from device knowledge and perform automation. The PLC will transfer collected data to different devices and receive knowledge and management commands from different devices through a port.
Protective Relay: –
A protecting relay is an IED designed to sense grid disturbances and mechanically perform management actions on the I&C system and therefore the grid to safeguard personnel and instrumentality. The relay has native termination so the copper conductors for every contact don’t have to be compelled to be routed to a central termination panel related to RTUs and PLCs. Transducers aren’t necessary since the relay accepts signals directly from the instrument transformers. protecting relays produce metering info, collect system standing info, and store historical records of power system operation.
Communications Processor: –
A communications processor may be a substation controller that comes with the functions of the many alternative I&C devices into one IED. it’s several communications ports to support multiple simultaneous communications links. The communications processor performs data acquisition and management of the opposite substation IEDs and additionally concentrates the information it acquires for transmission to 1 or several masters within and out of doors the station. The communications processor incorporates options of the many of the opposite IEDs as well as AN RTU, a communications port switch, a protocol entranceway, a time synchronization supply, and a restricted PLC practicality. The communications processor has locallyterminated I/O and might perform dial-out to alert personnel or processes once a standing changes.
Power Delivery Automation: –
Though each utility is unique, most consider power delivery automation of transmission and distribution substations and feeders to include.
- Supervisory Control and Data Acquisition (SCADA) – operator supervision and control.
- Distribution Automation – fault location, auto-isolation, auto-sectionalizing, and auto restoration.
- Substation Automation – breaker failure, reclosing, battery monitoring, dead substation transfer, and substation load transfer.
- Energy Management System, (EMS) – load flow, VAR and voltage monitoring and control, generation control, transformer and feeder load balancing.
- Fault analysis and device maintenance Systems without automated control still have the advantages of remote monitoring and operator control of power system devices including.
- Remote monitoring and control of circuit breakers and automated switches.
- Remote monitoring of non-automated switches and fuses.
- Remote monitoring and control of capacitor banks.
- Remote monitoring and voltage control.
- Remote power quality monitoring and control.
