شناسایی پارامتر کیفیت توان الکتریکی با استفاده از روش هماهنگ سازی جدید و ابزار اندازه گیری نوآورانه

The measuring and analysing of the quality and efficiency of electrical power usage is an important topic today and in the future. Electrical energy measurement must be synchronised with power frequency to analyse integer cycles and provide accurate power quality analysis. In this paper a new synchronisation method is presented which is realised from the software side without using PLL (Phase-Locked Loop). The paper also deals with real-time data processing, which is achieved with a multi-core personal computer (PC). In this way the power of the modern PC can be exploited in the area of electrical energy measurement. A measuring device was developed to implement the new synchronisation method and exploit the power of multi-core CPUs.
