GKS-SIS Type Plant Real Time Supervisory Information System
Introduction
GKS-SIS type plant real time supervisory information system is an integrated information system to realize the plant level information share and optimize the operation management of the power plants. This system integrates the plant level Management Information System (MIS), Unit real time control system that is distributed control system (DCS), accessory plant control system (PLC), electrical network monitoring system and energy measuring system, optimizes the integral supervisory and management level of power plants , and achieves the objective to increase efficiency with fewer employees.
GKS-SIS plant real time supervisory information system applies to power plants of different capacity.
Functions
- Real time supervisory data management.
- Equipment status detect, analysis and management.
- Plant performance calculation, and information statistics and analysis.
- Main auxiliary equipment fault diagnosis.
- Steam turbine generator units vibration analysis.
- Plant running cost optimization and economic load dispatching.
- Automatically bid on electric power market.
Features
- Layered, distributed, high-speed network structure. Interface layer network provides multi standard interface for connection with DCS and PLC network; application layer network can link various application servers.
- Database server with large storage capacity and advanced data compression method. Redundant configuration for important servers.
- Database supports multi platform structure. Database supports standard Client/Server structure and Multi-Server structure, and it has good openness and expandability.
- Adopt network visit priority monitoring technique and firewall technique to prevent of data loss, virus invasion and intentional destruction.
- The system has complete self-diagnosis function. It can automatically check or alarm when there is any hardware fault or software fault in the system, while the system's work status is not influenced.
- System has good expandability and further development environment.
