- Abstract:
- The paper deals with the problem of measuring harmonic and interharmonic pollution in electrical power delivery systems. The attention is specifically focused on the possibility of exploiting the compressed sampling in order to implement cost-effective nodes for distributed acquisition of the voltage signals. Differently from the traditional distributed measurement systems, the proposed approach should allow a dramatic cost reduction of the monitoring network. According to the compressed sampling protocol, the operations of distributed nodes will, in fact, be limited to random digitization and transmission of few samples for each voltage line; no high performance architectures should, thus, be necessary, with a consequent money saving. Assessing the compliance of the achieved measurements with the current standards turns out to be mandatory, thus verifying the absence of artifacts introduced by the adopted compressed sampling approach. Results obtained in numerical and experimental tests have highlight the promising performance of the proposed approach, thus suggesting its implementation in an actual measurement instrument.
