Problems In Parallel Debugging Of Diesel Generator Sets

Diesel generator set two parallel more and more widespread, often because of the increase in the demand for power and present the requirements of diesel generator set parallel services, with the development of modernization, the generator set is more and more used in national defense engineering, weapon system, field operations and other projects. In order to meet the requirements of large load or uninterrupted power supply, it is often necessary to operate two or more units in parallel. In parallel operation, the power distribution is often uneven. Excessive uneven power distribution will seriously affect the safety and reliability of the power station system, and will do serious harm to the generator set. It is the most common and difficult problem in the commissioning of parallel power stations. Based on the experience of commissioning parallel units, the technical staff of our company put forward the causes of circulation outbreak, some factors affecting the average power distribution and treatment methods.

Static analysis of circulation episodes

Taking the modular parallel control system as an example, the parallel debugging of the generator set generally balances the circulation when the parallel unit is in no-load parallel to meet the small and stable work, and then balances the active power through the load distributor. The key is to deal with the circulation problem when the parallel unit is in no-load parallel. Taking the parallel connection of two units as an example, the parallel connection of no-load usually presents the following problems:

(1) The circulation is too large and far exceeds 10% of the rated current of the parallel unit;

(2) After parallel connection, the circulation gradually increases with the working time until the inverse power alarm;

(3) The circulation is unstable, and the randomness is both large and small.
