Real Time Monitoring of HV Electrical Machines Driving Powerful Pump Aggregates

The paper summarizes our experience in building a system for real time monitoring of electrical parameters of powerful pump aggregates. The pumping station supplies cooling water for the main cycle of a power plant and is considered to be a part of the safety systems of the plant. The monitoring of the pump aggregates had to be realized not as an independent system but as a "patch" to the existing system for monitoring of the power supply of the station. The measurement capabilities of the existing devices are used. A set of issues with significant impact on practical realization of such a system are discussed here.
