Some Consideration about the Practical Design of the Diesel Engine Generator in a Hybrid System as a Power Supply in Telecom Plants

In this paper are considered parameters to be taken into account for a first approach design of a group thermal engine Diesel type coupled with an electrical generator. Some considerations are made about little electrogenerator groups due to the importance of their utilization in the photovoltaic and aeolian hybrid systems. So, tables are tentatively formulated with a practical character for a quick design of the systems. All calculations are made in view of a given use of the station battery by the optimization of its work, taking into account all the efficiences involved, in the case of power supply of telecom load operating in c.c. or c.a. modes.
