"Recycling the electric energy generated by the diesel generator set test, and then 'reversing' to the factory production equipment, to achieve arbitrary switching between the mains and generator sets, to provide electrical energy for the production equipment, and to ensure that the test conditions of the generator set meet the test specifications. The enterprise self-power supply forms a virtuous circle between production and kinetic energy protection systems." Nowadays, this idea has become a reality with the acceptance of the Hechai Heavy Industry Diesel Generator Setback Project.

The implementation of the diesel generator set return utilization project by Hechai Heavy Industry has a profound production base and industry advantages. Hechai Heavy Industry Co., Ltd. is engaged in the research and development of high-speed and high-power generator sets (87kW-2000kW). The products have a high reputation in the industry and are widely used in marine, civilian, marine, marine and offshore platforms. In the production organization, the enterprise implements strict quality standards, and each unit (set) must pass the test and verification to form a factory file and then deliver it to the user. Therefore, each (set) genset test will continue to test the whole machine for more than ten hours to hundreds of hours according to different requirements, thus generating a large amount of electric energy in the test. In the past, this kind of electric energy was converted into heat energy by circulating water.

With the development of science and technology and the country's development strategy of implementing green energy, energy conservation and emission reduction, Hechai Heavy Industry Co., Ltd., with the strong support of CSIC Heavy Industry Group, the diesel generator set returning power utilization project was established and gradually implemented. In order to continuously and steadily use the results to maximize the efficiency of returning electricity, Hechai Heavy Industry will form operational specifications for power generation equipment, formulate power transmission equipment control procedures and standard processes, and gradually expand the use of power after the supporting system is more perfect. Use range.

Hechai Heavy Industry became the first enterprise in China to successfully implement the diesel generator set return utilization project. It is a new breakthrough in energy utilization after implementing distributed energy technology and electric push technology, which is of great significance. This technology will not only bring better benefits to enterprises, but also add new ideas and new ways for domestic generators to form energy-saving emission reduction, cost reduction and environmental protection production.
