Objectif
Aim of the project is the design, installation and operation of a 15 kWp multi-purpose PV plant on the campus of the Faculty for Science and Technology of the New University of Lisbon, (FCT-UNL) in Portugal, combined with the development of an expert system providing criteria for the design of PV pumps systems.
A 15 kWp multipurpose photovoltaic (PV) plant is being designed, installed and put into operation on the campus of the Faculty for Science and Technology of the New University of Lisbon, (FCT-UNL) in Portugal. An expert system is also being developed to provide criteria for the design of PV pump systems.
The plant, which is designed as a stand alone system, will actuate water pumps for irrigation purposes. PV pumps, for technical reasons, cannot consume 100% of the PV generator output. For maximum utilization of surplus energy from the PV field additional consumers such as electrical power for tools, energy for a campus lighting system or back up electrical energy for sensitive electronic equipment in case of grid failure may be added to the system.
The central part of the system is an intelligent freely programmable load management system which will ensure optimal use of the energy supplied by the solar array. The lay out of this system is such that it offers the highest degree of flexibility for easy adaption to varying load profiles due to seasonal alterations or introduction of unpredicted loads.
A data acquisition system allows the monitoring of energy utilization and distribution. Results of the work serve as models for independent PV-powered grid systems supplying consumers of different priority levels in industrialized countries as well as for third world applications.
The plant has been built and is operating correctly. A personal computer (PC) based programme to simulate pumping systems was developed and validated. Work on developing the expert system is in progress.
The plant, which is designed as a stand-alone system, will actuate water pumps for irrigation purposes. PV pumps, for technical reasons, cannot consume 100% of the PV generator output. Therefore, the main aim of the project is the maximum utilization of surplus energy from the PV field by usefully combining with additional consumers such as:
- electrical ac power for tools
- energy for a campus lighting system
- optionally : back-up electrical energy for sensitive electronic equipment in case of grid failure
Central part of the system is an intelligent freely programmable load management system which will ensure optimal use of the energy supplied by the solar array. The lay-out of this system is such that it offers the highest degree of flexibility for easy adaptation to varying load profiles due to seasonal alterations or introduction of unpredicted loads.
A data acquisition system will allow the monitoring of energy utilization and distribution. Results of the R&D work can serve as model for independent PV-powered grid systems supplying consumers of different priority levels in industrialized countries as well as for third world applications.
The work will be carried out in two main phases: after a first phase of design and installation, the plant is scheduled to be operational by the end of March 1991. In the ensuing second phase the programme of the load management system will be continuously optimized to incorporate the operational experience acquired.
Simultaneously a computer programme is being developed where the state-of-the-art expertise in the field of PV pumps will be compiled. This expert system will allow a simulation considering several input variables in order to ensure optimal planning with respect to technical performance and costs of PV pumping systems.
