Insulation parts exist in dc wall bushing. During normal operation, insulation parts through the constant current conduction cannot as ideal insulator, so can't simply calculate the electric field in electrostatic field theory, otherwise cause calculation error, and even made bushing structure design errors. In order to study the ac and dc field different influence on bushing electric field. The calculation...
This paper describes the database approach of inspection robot for power transmission lines, discusses the issues which should be considered in developing a database management system of an inspection robot. The practical use of the database management system, together with an expert system is contributed to the inspection task of power transmission lines.
Reactive power optimization of power system is a dispersed, many variables, many restraint and non-linearly combination optimization problem, so it is very difficult to find optimum solving in theory. This paper combines Multi-Agent theory with the CGS-MSM PGA together, and make a certain improvement to heredity operate, set up a kind of improvement CGS-MSM PGA based on Multi-Agent, this algorithm...
Though the research of relay protection of power system has already passed certain period, but at present, the relay protection of power system still exists some problem such that the mend time is too long, regular protection value can't meet dynamic change of system, the detection means of trouble is limited and the judgment and location of trouble is difficult, etc. In order to solve these problems...
