The subject of paper is the methods of solving the actual problem of control the air gap in the hydrogenerators. These methods are used for improve the efficiency work of the hydrogenerators and reduce downtime caused by unscheduled repairs. In case high efficiency control is possible to transition from the planned repairs to repairs according to the the actual state of the generator. The methodology of problem solving in the paper. To solve the problem of control the air gap in the hydrogenerators use computerized specialized measuring control system. In this sуstem can perform analysis of changes in the air gap for each pole of the rotor used specialized software. The objective of the paper. The objective of this paper is to develop hardware and software solution for computerized control system of the air gap in the hydrogenerator for improving the efficiency of control. Foranalysis the changes in the air gap for each pole of the rotor in the system use specialized development software. For obtain measurement data proposed to use an original capacitive sensor that is adapted to the conditions and structural features in the hydrogenerator. Installed sensors is enables to control value of the air gap in the hydrogenerator. Sensors are located in a horizontal plane of 900 at an angle to each other. Solution. Use the computerized measuring equipment with specialized capacitive sensors as primary sensor is the perspective direction for building the systems of control the air gap in the hydrogenerator type СГК 538/160-70M. To convert the analog signal of the capacitive sensor into digital code while maintaining the measurement range is used Capacitance-to-Digital Converter with Temperature Sensor AD7745. For construction of the hardware control system uses original capacitive sensor in combination with Capacitance-to-Digital Converter. For construction of the developed software for control system used graphical development environment LabVIEW. Conclusions. The results of experimental laboratory research proposed and developed software and hardware control system of air gap in the hydrogenerator confirm–working ability the proposed solutions;–possibility for application the proposed and developed software and hardware solution for development the computerized control system the air gap between the stator and rotor in the hydrogenerators in the range 6 ± 4 mm of air gap.
