A Simple and Fast Voltage Disturbance Detection and Voltage Reference Generation Approach for Dynamic Voltage Restorer (DVR) to Compensate Unbalanced Voltage Sag and Swell in Three-Phase System: Simulation and Experimental Testing
Main Article Content
Abstract
The dynamic voltage restorer (DVR) is an important device for coping with voltage sag, swell, and unbalance. However, it is a real-time mechanism and must operate as quickly as possible to protect the sensitive and critical load from supply-side voltage anomalies. Hence, fast detection of voltage disturbances and reference voltage generation is essential for the DVR. This paper proposes a simple and fast voltage disturbance detection approach based on a simple three-phase phasor diagram which is easy to implement. The controller employed for the DVR uses a sliding mode control, making the entire system robust and insensitive to system parameter variations. Three different scenarios are simulated according to arbitrarily imposed supply conditions, verified in laboratory tests using the DSP R&D controller board. The results demonstrate a simpler, faster voltage-anomaly detection process which is easier for implementation compared to the other methods in the literature. The best and worst detection times (DTs) of the proposed approach are 1 and 4 ms, respectively. It yields a rapid response, accurate compensation, and robustness in restoring the load voltage to its nominal value within two cycles.
