Substation simulation experimental device

 

The system consists of three parts: a system screen, secondary protection cabinet, and a substation background system. At one time, the system uses a typical 110kV substation project as a model. There are two m--n variants, both of which are equipped with pressure -regulating types; two -way entry line, 110kV side and 10kV side use single -parent segments, 35kV side uses single -parent segment bands using single -parent segment bands The mother wiring. All the second parts use the micro -model relay protection device and measurement and control device, which are divided into four protective cabinet installations; the data can be uploaded, the monitoring host command can be accepted, and the requirements of the "Four Yao" function and remote mobility are fully met. At the same time, multi -serial cards are used to solve the problem of communication bottleneck between the protection device and the background system.

1. Experimental purpose:

Aerobic biological treatment technology is not only used for organic sludge and high concentration organic wastewater, but also can treat low concentration sewage. Compared with aerobic biological treatment technology, anaerobic biological treatment has high organic load, low sludge yield, energy consumption, energy consumption A series of obvious advantages.
