Welcome to Virtual Labs

Physical distances and the lack of resources make us unable to perform experiments, especially when they involve sophisticated instruments. Also, good teachers are always a scarce resource. Web-based and video-based courses address the issue of teaching to some extent. Conducting joint experiments by two participating institutions and also sharing costly resources has always been a challenge. With the present day internet and computer technologies the above limitations can no more hamper students and researchers in enhancing their skills and knowledge. Also, in a country such as ours, costly instruments and equipment need to be shared with fellow researchers to the extent possible.

The armature of the DC motor is fed from a (controlled) three phase thyristor rectifier. The DC voltage to motor field is also provided by a similar controlled rectifier. All the interconnections of the components are made inside the panel. A measurement card is enclosed inside the panel, which is used to measure and scale down the voltages and currents of the motor and generator.

Virtual lab Setup

The setup consists of a controlled prime mover (DC motor - separately excited) coupled to a synchronous generator which is to be connected to a power grid. The synchronous generator is excited by a controlled AC-DC power electronic converter. A separately excited DC motor is used as a prime mover. The armature of the DC motor is fed from a (controlled) three phase thyristor rectifier. The DC voltage to motor field is also provided by a similar controlled rectifier.

QNX

QNX is a commercial Unix-like real-time operating system, aimed primarily at the embedded systems. As a microkernel-based OS, QNX is based on the idea of running most of the OS in the form of a number of small tasks, known as servers. This differs from the more traditional monolithic kernel, in which the operating system is a single very large program composed of a huge number of "parts" with special abilities.
