Solar photovoltaics in Malta have increased substantially over the years, both at large scale and residential scale. The present installed capacity is already having a negative impact on Malta's’ grid infrastructure, causing problems due to the reverse power flows (resulting from oversupply) and related issues such as voltage rise. This paper considers the integration of a low voltage regulator in a low voltage feeder in a semi‐rural area in Malta. A thyristor‐controlled transformer‐based low voltage regulator was modelled and simulated in MATLAB/Simulink using the PLECS blockset. Experimental results were also obtained via measurements of the voltage profiles at 70% of the actual low voltage feeder that showed several instances of over and under voltage events. The outputs obtained from the simulation model strongly agreed with those obtained from the field testing thereby validating the simulation models that were developed in this study. Results show that the voltage on the feeder was successfully regulated to around the nominal voltage of 240 V. The regulator failed to correct the voltage to within ±10% in one occurrence where the load demand and hence the voltage drop was too high.

THE PURPOSE. To develop a stand for the study of the operability and quality of functioning of electrical complexes and electric drive systems with frequency regulators that have undergone major repairs.METHODS. When solving this problem, the method of direct evaluation of the mechanical characteristics of the system Source-Frequency ConverterMotor-Load was used, methods of direct evaluation of input parameters with subsequent calculation of indicators, methods of increasing algorithmic redundancy, mathematical methods of checks, logical control methods and complex control methods (the method of control tests, the method of control programs) were used. RESULTS. The analysis of test methods of frequency regulators was carried out, the necessary equipment was selected, stand control algorithms were determined, design documentation was developed, a stand was made to study the operability and quality of functioning of electrical complexes and electric drive systems with frequency regulators, the software of its control system was debugged, frequency converters were tested according to the developed methodology in accordance with GOST requirements.CONCLUSION. One of the most effective ways to determine the state of the frequency controller before sending it for installation is to check on a test bench to determine the degree of operability of the control and protection system, as well as the power part. The developed stand makes it possible to solve a wide range of tasks for the study of the operability and quality of functioning of electrical complexes and electric drive systems with frequency regulators that have undergone major repairs.
