CPL has inaugurated the largest agricultural biomass biogas power plant in Italy. Nine hectors of ground area, with Four 1 MWe power stations provide a total of 4 MWe generated electricity for 10,000 households a year with zero emissions. The largest agricultural biomass for biogas power production plant in Italy, engineered with the CPL Concordia technology, was inaugurated at Bondeno (FE) by Paolo De Castro, the president of the European Parliament Agriculture and Rural Development Commission in Italy.
“CPL Concordia was chosen for this project as unique solution providers for the four electric power station systems,” said Roberto Loschi, manager, CPL Cogeneration and renewable Energy sector. “Thanks to more than thirty years experience in the renewable sector, our company has been able to provide a product that can adapt to the different characteristics of the two chosen companies who supply the anaerobic digesters.”
The main objectives of this project were to protect the environment and stimulate agricultural production and to achieve this they first had to guarantee zero CO2 emissions into the atmosphere. This was achieved by developing a mechanism in which the four power stations work in harmony with the plant growth cycles based on the principle that carbon dioxide emitted by combustion engines is equivalent to that absorbed by cereal plants during their plant cycle whereby a zero balance effect is created between the two entities of CO2 emissions into the atmosphere.
The plant systems are composed of four SINCRO 1000 cogeneration 999 kWe modules programmed to work at least 8,500 hours a year. Estimated Energy generated is equal to more than 8 million kWh for each motor, for a total of 32 million kWh. The plant system uses Jenbacker JGS 320 GSBL motors version C25 that offer extremely
Particularly important is the plant’s automation system essential for monitoring, efficient management and maintenance, as well as analyzing historical system performance data. The plant supervision system is based on the Movicon 11 SCADA/HMI platform consenting management and complete monitoring and control locally or via web.
Each motor is equipped with a local control panel to monitor and control the running of motors using a PLC. CPL Concordia has applied each motor with a local supervision workstation, which responds to the main centralized supervisory system housed in the onsite technical building that serves as the control centre for running the entire plant complex.
Engineer Alessio Vaccari, head of the CPL Congeneration software department carried out a technical survey to evaluate the most suitable software platform to use. He chose the Movicon 11 Scada/HMI technology judged as being well suited for achieving the company’s set objectives.
The four local workstations with touch screen PCs communicate with the motor’s PLCs to collect all operating statuses, alarms and alerts, together with all electric power, heating and process measures including data on the amount of gas produced by the anaerobic digestors.
All the data is stored in a SQL Server database locally for analyzing electricity yield performance trends (power, voltage, current) and the motor working parameters (alternator and cylinder temperatures, water and oil temperatures and pressures) Thanks to the Movicon Data Analysis tools, the recorded measures can be instantly extracted from the DB archives and effectively represented by applying filters, zooms and using curve overlapping tools along with a variety of other analysis functions.
Purposely designed reports have been provided within the Movicon Report Designer to represent data summaries by exploiting a selection of charts and tables that can then be previewed and printed as pleased.
Another particularly useful tool is the Movicon Web Browser that can be used in screen pages to connect and display dynamic HTML pages provided by the motor builders to display different parameters showing essential functional motor details for maintenance staff to analyze.
To compliment efficient management and maintenance, the inbuilt Movicon data analysis tools are efficient in visualizing historical DB data according to client needs. System access is protected and regulated by a Login procedure based on pre-assigned security level and password.
In addition to the statistical information, there is also an alarm management, which has been designed for easy use and consultation with options to send notifications automatically via SMS using SM modems enabled for each motor together with the Movicon Alarm Dispatcher.
The Main Movicon Supervisor, housed in the technical control center, simply offers centralization of data deriving from each local workstation. Control center engineers can view all information on individual motor separately or altogether in one display with overall parameter aggregations. Data is also stored in the control centre on a relational DB based on SQL Server in the main supervisory workstation. As the power plant site covers quite a large area of ground (1.2 square Kms) each motor is connected to a public ADSL network using a Static IP address. This allows access to the supervision system via internet possible by using the built-in Movicon Web Client.
Web access to the system not only consents CPL Concordia, but staff or clients as well, wherever and whenever, to connect to the power plant system to check data and working statuses. In addition to all this, the CPL Concordia technicians have been exclusive permission to remote access the PC for maintenance purposes and interventions
CPL Concordia has dedicated a team of 30 personnel, which include technicians, design engineers and maintenance staff, under the co-ordination of Project Manager Gianni Pezzetti. the clients have also entrusted CPL with the management and full service maintenance of the power stations for the next 15 years. This acknowledgment is linked to the 96 percent guarantee offered by CPL for the running of these power stations as well as the company’s 30 years experience in the cogeneration sector (over 400 plant systems have been installed in Italy alone) which comes with the Post Sales Services offered to clients by CPL Concordia.
