This paper concentrates on delving distribution network. Based on analysing
distribution-network features. distribution outomation development at home and abroad,
a general design is proposed. Its architecture is a layered and distributed opening system
based on power line carrier technique. Distribution automation is a large scale system
including computer、communication and electric power system technology It is a modern
subject for city and countryside power distribution reconstruction in China. Developing a
suit of reliable. flexible. expandable、convenient using 、maintainable and powerful
functions distribution automation system is an urgent task for city and countryside power
distribution reconstruction in China at present.
The key problem of distribution system is communication. In this thesis, a network-
distribution line carrier (NDLC) communication system based on Digital Signal
Processing (DSP) technology is introduced and implemented, Which is suitble for the
protection and control of distribution systems. The characteristics and channel attenuation
of distribution system line carrier communication are analysed. Some practical measures
are studied in order to improve the relibility of NDLC system and networking princiles
are also provided for the distribution line carrier communication system. Communication
processor is a connecting link between the preceding and the following device in the
distribution system communication. It transmits remote control and communication
information. In this thesis, a communication processor software-based IEC870.5-101
transmission protocols and DNP3.0 is designed and programmed.
The distribution automation system takes advantage of the world softwares design
ideas. In this thesis, the emphase is designing and programming the real-time database
(RTDB). The new idea Which electric power systems facilities regarded as nodes is bring
forward. Based on the node, a new share memory design for distribution automation
database conjoining real-time database to commericial database is introduced and
implemented. On the other, a technique-dynamic link library (DLL) accessing database
is adopted. The software of real time database (RTDB) and DLL are implemented with
VC++6.0.This distribution automation system has good reliability、 flexibility and
opening.
