The main achievement is as following: Present a new software structure with insert mode based on diagram and data platform. With this structure the software can be used in various voltage levels of power networks by switching function groupware with corresponding edition. Therefore it is important to solve software universality and developability.(2) Present a new idea that any operating condition is combination of running mode of plant or station, power supply topological and rules of equipment maintenance. This idea is very useful at simplifying setup and choice of operating conditions and ensuring calculation result correction.(3) Present a new idea of protection setting examination and rectification. Protection setting examination is used to examine the selectivity、 sensitivity and speed under certain operating condition, and pass an opinion whether these settings are wrong;Setting rectification is used to calculate new relay settings when error is found in setting examination.(4) Point out that interaction design is the key step in developing power system application software,which can secure usability.

As a private mobile communication system, The digital trunkingmobile communication system was boomed in 1990's, and before this, the appliedprivate mobile communication systems in market are almost the analog systemwith analog voice and digital signalling. And there are no data referring to thesystem design and parameters chosen. It includes the wireless channel accessalgorithm of the mobile terminals, single base station capacity in large regional networks, link designing schemes between the switching control center and basestation as well as the study of the service quality for the multiple traffic. Theseindispensable parameters in design a digital trunking communication system arestudied in this dissertation and some instructive achievements can be got. To provethe correction of the theoretical study, the result was tested with the popularsystem of pan-European digital trunking communication system.
