Upcoming Projects

SPPA-T3000

SPPA-T3000 is a process control system for power plants developed by Siemens, and is the successor to the SPPA-T2000. In contrast to previous process control systems, SPPA-T3000 does not use bus protocols for data transfer such as Profibus, Modbus or LON. It uses modern computer technology instead, specifically TCP/IP ethernet-based networking. This translates to a larger benefit: SPPA-T3000 is a software based solution, and is therefore cross-compatible with many different types of hardware.
The acronym SPPA stands for Siemens Power Plant Automation. The SPPA-T3000 itself, is part of a platform that consists of several components:

  • SPPA-P3000 (Process Optimization for Hardware elements of a power plant)
  • SPPA-D3000 (Diagnostic Solutions: Machinery Protection, Machinery Analysis and Plant Monitor)
  • SPPA-M3000 (Energy Management Suite)
  • SPPA-E3000 (A set of solution tools for the electrical components)
  • SPPA-R3000 (Gas and steam turbines' control technology)

History

Developing the SPPA-T3000, Teleperm M was one key step in the 1980s. It was one of the first computerized control systems. Its successor, Teleperm XP, was later renamed SPPA-T2000. In the beginning, SPPA-T2000 was based on SIMATIC S5 controllers. Subsequently, Siemens integrated the next generation SMATIC S7 which is still used today.

Components

The SPPA-T3000 software architecture consists of several components. Due to their JAVA characteristics, these components can be freely distributed to any hardware platform. Typically, the SPAA-T3000 is set up with a SPPA-T3000 desktop interface, application and technology servers and real-time automation servers. SPAA-T3000 uses the following software standards: JAVA, Ethernet, XML, HTML, IEC 61850, Windows and Profibus DP.

Type Description
JAVA Programming language in SPPA-T3000
TCP/IP, Ethernet Enables communication between various systems
XML Global data format used to archive configuration data and as access point for import and export
HTML Homepage to access desktop interface
IEC 61850 Used for the integration of electrial systems and components
Profibus DP Used for a flexible and independent E/A-Connection


  • Desktop Interface

Various user interfaces within the SPPA-T3000 are made accessible via a web browser. Staff can use the system from the plant’s control rooms or through a secure internet connection.

  • Server

The SPPA-T3000 Server consists of two hardware platforms controlling and carrying out system related tasks. The automation server provides the automation functions as well as the E/A-Connection. The automation server’s systems are built up according to the redundancy concept. Essential elements, such as CPU and power supply, are in place in duplicate. Additionally, the automation server is based on SIMATIC S7-CPU and TÜV certified (SIL 1 to SIL 3 according IEC 61508, requirements of class AK 1 to AK 6 according DIN V 19250/DIN V VDE 0801 and category 2 to 4 according EN 954-1). The application server shows characteristics both of an application server and a technology server. While the application server controls applications, such as webserver and a central project container, the technology server is equipped with a runtime environment used for diagnostic tasks.

  • Networks

System data are distributed within the SPPA-T3000 with the help of ethernet networks or Profibus DP. A high speed Ethernet transports data and sends them from the automation server to the application server where they are made accessible on the connected user interfaces. Profibus DP is a standardized norm (norm EN 50170 and IEC 61158) which is met in various end devices.

  • Process Interface

The hardware connection between field- and process level is described as process interface. It transports the manually or automatically generated tasks to the field level. SPAA-T3000 Process Interfaces can be split up in different set up groups, such as ET 200M HART AI or E/A FUM.

Architecture

Using internet technologies has led to two different lead technology systems, the field level and the IT level.
