For some years now, power generation and distribution have been undergoing major changes.
The innovation cycles (where operating equipment and communication media are concerned) are getting ever shorter, and the market is becoming increasingly deregulated.

SICAM PAS (Power Automation System) meets all the demands placed on a distributed substation control system - both now and in the future. Amongst many other standardized communication protocols, SICAM PAS particularly supports the IEC 61850 standard for communication between substations and IEDs. SICAM PAS is an open system and - in addition to standardized data transfer processes - it features user interfaces for the integration of system-specific tasks and offers multiple automation options.

Providing an innovative solution such as various tasks to a distributed information system, our ECMS is an adequate system for fields of manufacturing fields, power plants, and substations. Designed as an open system compatible with wide-spread used communication standards, SICAM PAS product is modular. As elaborate Human-Machine Interface (HMI) development software, SICAM PAS CC provides many options for various system maintenance and management with various operation options.

Through Simple Network Management Protocol (SNMP), rapid fault detection and a credibility of operation are provided, plus DNP 3.0 and other different communication regulations. And it applies to power plants and control monitoring systems of substation, so as to provide an economical solution that enhances efficiency of each electrical power facilities.

• SICAM PAS is an energy automation solution; its system architecture makes it scalable.
• SICAM PAS is suitable for operating a substation not only from one single station level computer, but also in combination with further SICAM PAS or other station control units.
• Communication in this network is based on a powerful Ethernet LAN.
• SICAM PAS controls and registers the process data for all devices of a substation, within the scope of the data transfer protocols supported.
• SICAM PAS enables integration of a fully graphical process visualization system directly in the substation.
• SICAM PAS simplifies installation and parameterization of new devices, thanks to its intuitive user interface.
• SICAM PAS is notable for its online parameter setting features, particularly when the system has to be expanded.
• SICAM PAS features integrated testing and diagnostic functions.
• Its user-friendliness, its operator control logic, its orientation to the Windows world and its open structure ideally suit users’requirements.

SICAM PAS works on industrial-standard hardware with the Microsoft Windows operating systems. The advantages of this platform are low hardware and software costs, ease of operation, scalability, flexibility and constantly available support. With the powerful real-time data distribution system, applications can be allocated among several computers, thus boosting performance, connectivity and availability.

A database system stores and organizes the data basis (e.g. configuration data, administrative status data, etc). The device master function for communication with Intelligent Electronic Devices (IEDs) supports a large number of well established protocols. The SICAM PAS data normalization function allows conversions such as measured-value filtering, threshold value calculation and linear characteristics. SICAM PAS CC is used for process visualization. Specifically designed for energy applications, it assists the operating personnel in optimizing the operations management. It provides a quick introduction to the subject matter and a clearly arranged display of the system’s operating states. SICAM PAS CC is based on SIMATIC WinCC, one of the leading process visualization processes that is used in industrial automation worldwide.

To facilitate incident analysis, the fault recordings from protection units are retrieved and archived automatically during operation. This is particularly supported for the standard protocols IEC 61850 and IEC 60870-5-103, but also for PROFIBUS FMS (SIPROTEC 4). Fault recordings are visualized and evaluated with the program Comrade View as standard. Alternatively, SIGRA 4 with its additional functions can also be used.

In a substation which configure and operate with SICAM PAS, various types of protection units, IEDs, bay control units, measuredvalue recorders and telecontrol units from a wide range of manufacturers can be used. SICAM PAS offers a large number of commercially available communication protocols for recording data from various devices and through differing communication channels.

• SICAM PAS operates on the basis of Microsoft Windows operating systems. This means that the extensive support, which Windows offers for modern communication protocols, is also available with SICAM PAS.
• SICAM PAS was conceived for easy and fast integration of conventional protocols.
• Standardized TELECONTROL PROTOCOLS
  - IEC 60870-5-101
  - IEC 60870-5-104
  - DNP V3.00, TG8979, DCT
• SICAM PAS can also be set up on computers networked with TCP/IP. Here, one computer performs the task of the so-called Full Server.
• SICAM PAS allows use of the SICAM PAS CC process visualization system for central process control and monitoring.
• For industrial applications, it is easy to configure an interface to process visualization systems via OPC (object linking and embedding for process control).
• SICAM PAS can be configured as an OPC server or as an OPC client. The SICAM PAS process variables ? available with the OPC server ? can be read and written with OPC clients working either on the same device or on one networked by TCP/IP. The OPC server is included in the basic system. The OPC client is available as an optional package. A typical application could be the connection of SIMATIC programmable controllers.

During e.g. maintenance work or for other operational reasons, information exchange with the control centers or the substation itself can be blocked with the telecontrol blocking and bay blocking functions.

The telecontrol blocking function can also be configured for specific channels so as to prevent the transfer of information to one particular control center during operation, while transfer continues with other control centers. The bay blocking and telecontrol blocking functions act both in the signaling and the command directions.

Channel-specific switching authority also makes it possible to distinguish between local control (SICAM PAS CC) and remote control for the switching direction, but also between control center connections. Circuit-breakers can be controlled in synchronized/unsynchronized mode.

Automation tasks can be configured in SICAM PAS with the CFC (Continuous Function Chart), which conforms to IEC 61131. In this editor, tasks are configured graphically by wiring function blocks. SICAM PAS comes with an extensive library of CFC function blocks, developed and system-tested especially for energy automation.
SICAM PAS features comprehensive redundancy functions to boost the availability of the station automation system:
SICAM PAS CC communicates simultaneously with both redundant station control units. A redundant structure is also possible for process visualization with SICAM PAS CC and fault-record archiving with SICAM PQ Analyzer

The amount of information to be processed by SICAM PAS is essentially determined by the following factors

In the operation of a substation, SICAM PAS is used for configuration purposes and as a powerful data concentrator. SICAM PAS CC serves as the process visualization system. In the signal lists, the original time stamps are logged in ms resolution as they occur in the devices. With every signal, a series of additional data is also presented to provide information about causes (spontaneous, command), event sources (close range, local and remote), etc. Besides process signals, command signals are also logged.

IndustrialX-Controls are used to control and monitor the switching devices. These switching device objects support four different forms of presentation (IEC, DIN, SINAUT LSA, SICAM) for circuit-breakers and disconnectors. It is also possible to create bitmaps (defined for a specific project) to represent the switching devices, and to link them to the objects. For informative visualization, not only nominal and spontaneous flashing are supported, but also the display of various device and communication states (e.g. up-todate/ not up-to-date, bay and telecontrol blocking, etc.).

Connected with SCAM PAS units, switching devices are directly or controlled by “SELECT BEFORE OPERATE”mode. Topological Coloring is used for a single line image process, and through internet control and monitoring are implemented. A calculated value analysis by using SICAM VALPRO function, a fault record data collection and saving function in protection relay by using SICAM RECPRO function can be implemented.

SICAM PAS CC is based on SIMATIC WinCC, it has the following impressive features:

The SICAM PAS user interface is based on customary Windows technology, which enables you to navigate in the familiar Windows environment both when configuring the system and during ongoing operation. The system distinguishes between configuration and operation of a substation. In SICAM PAS, these two tasks are firmly separated by two independent programs.
THE SICAM PAS UI - CONFIGURATION program is used to create and edit a project-specific configuration. To enhance clarity, several views are distinguished

A common feature of all views is that they have an Explorer window that shows the system configuration in a clearly arranged tree structure. As in the Windows Explorer, you can open individual levels of this tree structure to work in them. You work through the necessary steps in the data window on the right. Here, you set parameters, select information and define assignments to a user-specific, process-oriented system topology. The user interface is uncomplicated and structured according to the task definition, so as to enable intuitive working and to simplify changes. The user interface assists the editing process by displaying parameter descriptions and messages when incorrect parameters are entered. In the tabular views for information assignment and allocation to the system topology, configuration is made easy by extensive sorting and filtering mechanisms, multiple choices and Drag &Drop. To ensure data consistency and to avoid redundant data input, SICAM PAS UI provides extensive import and export functions for the exchange of configuration data, e.g. with the bay control level and with process visualization.
