Specialized analyser for electrical energy quality estimation in ship electrical power system

This paper presents the problems of electrical energy qualify estimation in ship electrical power system and describes the appropriate factors of this. These factors were worked out with criterion of safe operation of ship technical systems Economical aspects of the presented problems have only auxiliary importance. Special attention has been pain to instrumentation for electrical energy estimation In this context, the concept of specialized analyser for electrical energy quality estimation is shown, The presented device was constructed with its own safety operation criteria and destined for use under assumption of temporary lack of service. For this reason, it has particular, distributed structure which contains autonomous modules. Moreover, some additional autodiagnosis and emergency functions have been introduced Taking into account measurement needs the signal processors application for analyser construction has been proposed.
