Kurochka V. Methods and means of monitoring the insulation and leakage current trolley

Object of the research - the process of major changes technical condition of electrical nodes trolleybuses; the aim of work is raising credibility of control isolation and leakage current of trolleybus by improving the methods and definitions funds condition of electrical insulation of major nodes and leakage current; using automatic control theory methods for analysis and improvement mathematics models control of isolation and leakage current; theory finite automatics for synthesis structure device control leakage current, fuzzy theory for building a multitude mathematics models, which prove adjusting values insulation, genetic algorithms - to adjust work fuzzy model; analytics abilities of computer algebra - for modeling dynamic processes; theoretical results - changes in voltage dependence installed on sample capacitor vessels such ohmic resistance insulation in circle which included, that the provisions in the framework of improving the method for determining the ohmic resistance, which excellence in such minimization effect of famous capacitor resistance to ohmic resistance insulation of trolleys. Detected patterns of changes voltage nutrition positively and negatively pole regarding the case in transient modes work electric drive where capacitors insulation resistance, which used for base of models mathematical isolation, that helps definite capacitors parts in resistance in its route not turning of trolleybus from the network. Detected dependence parameters insulation trolleys and systems nutrition from impact environment, namely temperature and humidity, which based to the method of adjusting parameters definition of insulation trolleys and systems nutrition. Improved methods of control leakage current, which provisions based device developments in excellence here of famous gives capability definite plot of crash isolation and raise the credulity of control leakage current of trolleys. Practical results - created computers model of control the leakage current of trolleys in environment Matlab Simulink, that allow quickly research mutual influence of nutrition and insulation system insulation on talk leakage current of trolleys. Designed structure scheme and algorithm work microprocessor device control and isolation leakage current of trolleys, that allow definite and adjust parameters insulation value, not turning off trolleybus from the network, control importance measured and definitely imitation leakage current, definite plot with crashed insulation of electrical equipment. Degree of introducing - the results of work in communal introdused the enterprise "Vinnitsa tram and trolleybus management" and in the academy process Vinnytsia National Technical University. Scope (area) uses of - enterprise, using electrical train.
