Objective
The performance of the 10 kWp solar power plant in Berlin has been assessed. The energy is stored in a battery with a capacity of about 100 kWh and was used to cover the electric demand of a heat pump and household and lighting appliances. A solar station for the purpose of operating an electric car has been added. A low loss control unit was installed to supply energy to the car, and a large system battery permitted complete charging of the car battery, of necessary. An intelligent control unit was used to supervise different charging procedures for the car, and the integration of a data logging system in the car permitted research on optimization of the effective range.
A procedure for determining the charge status of large battery installations was developed. Computer controlled remote reading of differential pressure measurements obviates the need for service staff to risk contact with hot components or acid. A measurement system for recording the voltage current characteristic of solar generators has been designed, using a low loss load simulator.
IN 1988 WE INSTALLED A PV PILOT PLANT WITH A TOTAL POWER OF APPROX. 10 KWP IN A RESIDENTIAL DISTRICT OF BERLIN (WEST).
THE ENERGY IS STORED IN A BATTERY WITH A CAPACITY OF ABOUT 100 KWH AND USED TO COVER THE ELECTRIC DEMAND OF A HEAT PUMP, HOUSEHOLD APPLIANCES AND LIGHTING EQUIPMENT.
ADDITIONALLY THE SYSTEM IS CONNECTED TO THE PUBLIC GRID TO FEED-BACK SURPLUS ENERGY.
THE MAIN GOALS OF THE PROJECT ARE:
- OPTIMIZATION OF DC/AC-CONVERTERS, REGARDING ON FAILURE PROTECTION AND HIGH PARTIAL LOAD EFFICIENCIES.
- DEVELOPMENT OF LOAD MANAGEMENT STRATEGIES FOR OPTIMAL USE OF SOLAR ENERGY.
- INVESTIGATION OF DIFFERENT OPERATION CIRCUMSTANCES ON LIFETIME AND EFFICIENCY OF THE BATTERY.
- OPTIMIZATION OF THE INTERACTION OF ALL COMPONENTS.
THE SYSTEM IS PROVIDED WITH A CENTRALIZED MICRO PROCESSOR SYSTEM THAT ENABLES AUTOMATIC OR MANUAL OPERATION OF THE SYSTEM.
IN 1989 A STANDARDIZED MEASURING SYSTEM WILL BE INSTALLED BY BMFT.
THE PROJECT IS SPONSORED BY THE COMMISSION OF THE EUROPEAN COMMUNITIES (CEC) AN THE MINISTER FOR RESEARCH AN TECHNOLOGY OF GERMANY (BMFT).ND TECHNOLOGY OF GERMANY (BMFT).
