Realizacja urządzeń automatyki elektroenergetycznej na bazie układów FPGA

摘要

W artykule opisano wykorzystanie układu FPGA do realizacji układu automatycznej synchronizacji prądnic. Zastosowanie układu FPGA zapewnia w pełni sprzętową realizację procesu synchronizacji. Gwarantuje to deterministyczną i niezawodną realizację procesu synchronizacji. Układ FPGA pozwala również na równoległą realizację poszczególnych zadań procesu synchronizacji.%In the paper there is described implementation of a power object automatic synchronizer with use of the FPGA chip. The FPGA unit is a programmable chip. It is equipped with a specific set of logic elements, among which you can define the network of connections (Fig. 1). In this way, a hardware implementation of the desired functionality of the system is obtained [3]. The task of the automatic synchronizer is to connect a synchronized power object to parallel work, according to the amplitude, frequency and phase conditions. Given the very serious consequences of erroneous execution of the synchronization process [1], automatic synchronizers belong to the group of devices which puts very high demands for reliability. Application of FPGA provides fully hardware realization of the synchronization process. The advantage is high reliability, resulting from elimination of layers of software, which can be a potential source of errors. Another advantage is the true parallel realization of each task of the synchronization process. Each task is carried out in parallel by separate blocks of logic elements, as shown in Fig. 3. This solution also provides fully deterministic execution of the program code. The developed synchronizer enables full registration of parameters of the synchronization process, which is realized by application operating on a PC. Communication between the synchronization process and the application takes place via the Internet and the mechanism of direct memory access DMA. The communication diagram is shown in Fig. 5.
