This study focuses on the design of a measuring system for monitoring the power quality within the SMART street lighting test polygon at university campuses with relation to testing an adaptive current control strategy for three-phase shunt active power filters. Unlike conventional street lighting, SMART elements are powered 24/7. Due to the electronic character of the power part of such mass appliances, there are increased problems with the power quality of the electric energy. Compared to the current concept of street lighting, there is a significant increase in the content of higher current harmonic components, which cause several problems in the distribution system. The test polygon contains 16 luminaires made by various manufacturers and mounted with various SMART components. Using the polygon control and monitoring system, dynamic load scenarios were selected. These scenarios tested the possibilities of different adaptive current control strategies for three-phase shunt active power filters to improve the power quality of electricity. This study focuses on three adaptive algorithms that respond to dynamic changes of current harmonics level in real-time. The possibility of active filter control was tested using FPGA, mainly due to the low latency of the filter control part.

Contrast Analysis

With the wide application of power electronic equipments in power system, more and more harmonic are poured into the power system, which cause power pollution and make the power quality problem increasingly serious. Active power filter (APF) is an important equipment to compensate harmonic and reactive current in power system. One of the key technologies lies in the real-time and accurate control. The fundamental principles of several control strategies of compensate current were presented, and the respective merit and demerit of these control strategies were pointed out with contrast analysis in this paper. Active power filter will achieve a higher performance and a wider application with the continuous development of the control strategy.
