1.overview
The CMS-4000 system primarily
achieves real-time monitoring of the power grid's operation by collecting
real-time data from various switches distributed throughout the distribution
network, particularly the protection behavior SOE information of the switches.
This enables operators and system dispatchers to promptly grasp the operational
status of the system, enhances the proactivity in handling incidents, and
improves the automation management level and power supply quality of the power
grid.
2.System Architecture
3.operating environment
-
Standardization:The system adopts various hardware and software platforms that adhere to
comprehensive, open, industrial-grade international standards.
-
Hardware Platform:The system supports a range of RISC-based servers and workstations, including
IBM AIX series, HP-UNIX series, and SUN-Solaris series, as well as Intel-based
PCs.
-
Operating System:The system utilizes UNIX that complies with the POSIX 1003.1 system server
definition standard, POSIX 1003.2 shell and utility service standards, and
POSIX 1003.3 portable operating system real-time extension standards. It
supports 64-bit operations and process management, as well as compatibility
with Windows XP and Windows 7 systems, allowing for a hybrid cross-platform
operating environment.
-
Network:The system adheres to the ISO-OSI seven-layer network reference model and
employs a dual-network mechanism with load balancing/redundancy, supporting
protocols such as TCP/IP, X.25, and PPP. It incorporates comprehensive network
security measures and facilitates distributed network applications.
-
Graphical User Interface
(GUI):The system is designed for
cross-platform compatibility, supporting X-Windows, OSF/Motif standards, and
MS-Windows standards. It features a standard API that allows for quick and
convenient porting between different platforms, along with a complete set of
development tools. The graphical interface supports vector-based Chinese
characters and multiple file formats.
-
Database:The system utilizes the standard Structured Query Language (SQL) and supports
ODBC. It is compatible with major commercial databases such as Oracle, Sybase,
and SQL Server.
-
Programming Languages:The system supports high-level programming languages such as C, C++, and Java,
utilizing QT for cross-platform technology. It complies with IEEE standards for
floating-point operations, allows for internal calls between different
languages, and provides shared functional library interfaces.
-
Geographic Information
System (GIS) Foundation Platform:The system
supports platforms such as ARCINFO and MAPINFO.The system's network and
host components comply with relevant international and industrial standards,
ensuring reliable interoperability with dispatch automation systems and
management information systems (MIS). Additionally, the application development
platform supports a high degree of portability, while the choice of network
protocols includes widely adopted standard protocols.
