High power quality level DC distribution system for woodworking plants

Abstract

Power quality is becoming more and more important for different kind of users. In particular, for industrial customers it represents a key factor for the productiveness and the efficiency. Also, the wide diffusion of electronic loads implies a spread use of power electronics. In this scenario, DC distribution networks are a suitable solution for solving problems of power quality both for the customer and for the supplier. In the paper, the opportunity of using a DC distribution network inside a woodworking plant is analyzed. A network configuration and a control strategy are proposed and verified by means of numerical simulations and experimental tests.

“…Usually, electrical drives alternating between acceleration and braking operations are the most diffused regenerative loads. For this reason, the test to simulate regenerative loads is conducted by applying the real power demand of an electrical drive for a woodworking plant [17]. The working cycle lasts 1.9 s, with an acceleration phase (maximum power absorbed 3.5 kW), constant speed phase (power absorbed 700 W), and braking phase (maximum power regenerated 1.7 kW).…”
