Research description
Multi-Agent and Intelligent Agent Techniques in the Control and Surveillance Telematic System of a Hydroelectric Power Plant Chain – AGENTEL
The telematic system assures the supervision and control of the Somes River basin. The Somes structure, the most important parameters of the reservoir’ structure, the common and specific functions of the reservoirs, the technical characteristics of the hydro-electric power plants: the installed power, the multiannual average energy, the multiannual average flow, the installed flow, the upstream level, the downstream level, the gross fall establish the correlation between the functions of each power station in the hydro-energetic system and the usage criteria of the hydro-energetic potential.
The SCADA system, implemented on the hydro-electric power plants chain of Somes, is the host of the programs based on multi-agent techniques and intelligent agents. The SCADA system includes the Local Data Collector subsystem, the Centralized Command, the Software sub-system that offers data structures, configuration and acquisition files and their type from the point of view of multi-agent systems.
The multi-agent society used for the monitoring of a hydro-power plant chain has certain characteristics that impose the need for the existence of a proper functionality of the multi-agent platform: communication, mobility, a coherent, flexible and intuitive type of action for the agents –ADK (Agents Development Kit).
The System’s Functions
The functions at the level of the hydro-electric power plants from the structure:
- Launching and transmitting operator commands from user interface screens
- Actualizing the synoptic schemes through acquisition of synoptic numerical signals in real time
- Primary processing of numerical and analog measurements in the hydro-electric power plant
- Warning the operator if a failure appears at the hydro-electric power plant
- Generating log files for acquisitions and event reports
- Recording the number of actuations for switches, the functioning period for some equipments and subassemblies for the administration of their revisions
- Posting the log files in graphic or table configurations, on the operator’s request
- Managing the communication with the superior hierarchical level
- Synchronizing the real time clock with the dispatcher’s clock
The functions at dispatcher level:
- Following the synoptic scheme of all the waterfalls’ power plants with the possibility of detailing the scheme of each hydro-electric power plant integrated in the telematic system
- Transmitting the commands to the switching equipments from the central dispatcher in real time
- Transmitting the commands for establishing the values P and Q from DH
- Continuously measuring the analog and numeric inputs and storing them in the log files of the measurements database
- Visualizing the analogical and numerical data from each hydro-electric power plant on the general synoptic scheme or on the synoptic scheme of the hydro-electric power plant
- Signaling in real time the appearance of some critical events of alarm or failure with visual and audible alert for the operator in all operator interfaces
- Communicating, tele‑transmitting and processing the data continuously acquired at the dispatcher
- Dynamic allocation of the names of the damage signals, events, monitored protections
- Generating log files with data, synthetic files with maneuvers and events for each of the hydro-electric power plants
Agent specific functions:
- Data acquisition by automatic scanning of files generated by the SCADA system
- Processing, formatting and encapsulation of data for persistent display
- Accomplishing “logging function” for each acquisition entity (agent)
- Assuring persistence of input data at a centralized database level, managed by Microsoft SQL Server 2000 DBMS
- On-line data display and integrated support for signal evolution histograms and reports
