Software testing plays an important role in early verification of software systems and it enforces quality in the system under development. One of the challenging tasks in the software testing is generation of software test cases. There are many existing approaches to generate test cases like using uses case, activity diagrams and sequence diagrams, they have their own limitations such as inability...
Software Requirements modeling is important for requirement understanding especially when they are expressed in Natural Language such as English, which is universally understood. Expressing requirement is such a way is natural and known to stakeholders. However, they are prone to ambiguity and poor understandability. This paper demonstrate how we can model software requirement expressed in natural...
As the electric power supplied by solar array is dependent upon the isolation, temperature and array voltage, it is necessary to implement Maximum Power Point Tracking (MPPT) in order to move the solar array operating voltage close to the peak power point, therefore drawing the maximum power from the solar array. The solar array shall be integrated with a DC-DC converter and a control algorithm to...
In this paper a photovoltaic (PV) 3-phase inverter system is simulated jointly with its control in PSIM software. The conventional PV systems of today can be costly and this likely prevents wide-scale interest in fully implementing solar PV solutions. The simulation of the system is developed for testing control algorithm before a real-time implementation. The inverter allows full control of reactive...
