The currently used test load of diesel engines and diesel gensets are dynamometers and water load. The mechanical energy and electrical energy are consumed by the water resistance, which lead to energy waste. Based on this situation, the technology of energy feedback type electronic load system for diesel gensets is studied. According to the test characteristics requirements of marine diesel gensets and AC gensets driven by reciprocating internal combustion engines, the technical program, system parame- ters and equipment modal selection are determined. Through the energy feedback type electronic load tests of a type of gensets, it is verified that the performance indexes of the developed energy feedback type electronic load system could satisfy the test requirements of speed governing and load characteristics of gensets, and could realize energy saving, cost reduction, and improve test efficiency of diesel gensets.
