PID-Based Electronic Load Controller for Three-Phase Synchronous Generator

This paper presents a project based on Proportional Integral Derivative (PID) for the implementation of load controller for 3-phase Synchronous Genera-tor. Electronic load controller is a device which is related with power elec-tronics method of controlling, managing and monitoring frequency of a sys-tem. Mostly, in ruler areas we don’t have access to grid for power. There Pi-co, micro hydropower can be implemented to provide power. For persistent operation and control of a 3-phase Synchronous generator, an electronic load controller has been implemented rather than using speed controller governor which is much more expensive. With the help of proposed device load out-put can be controlled and thus frequency can be maintained constant which again reduces worse case of overloading on generator. Therefore with the help of proposed scheme protection of both generator and users load can be maintained. Proposed system can play a vital role in run-off-river type hy-dropower station because there is no point of saving water. Thus the overall cost of installation of Hydropower plant can be decrease up to a large extent so the proposed system can be utilized in ruler areas where we do not have grid connection for Electricity.

Proposed System

powerful control

The main function of proposed scheme is that, it has the ability to draw different current from different phase of the generator terminals which allow it to compensate for the unbalanced consumer current. Therefore the frequency of the system is bal-anced. This feature results in generator currents being balanced even when consumer loads are unbalanced .Thus overloading of generator is also reduced. The proposed system is embedded with variety of sensors like Zero cross detector, Triac gate driv-er circuit, Frequency sensor, Current sensor, Notch detection sensor. The function of frequency sensor is to sense change in frequency at any instance of time. Current Sensor is used to calculate current in each phase. Zero cross circuit is used to detect correct timing for firing of TRIAC at certain delay or firing angle. Notch detecting circuit is used to calculate waveform’s ON and OFF time period to calculate exact firing delay.

Conclusion

Powerful control developed By Kamran

By the use of PID based Electronic load controller we can easily control and monitor frequency of the generator. We can reduce worse case of overloading on generator. Therefore there is very less risk of damage of generator which is very costly. Thus, Frequency can be maintained constant with least error. Since this is an era of science and technology, we will make better monitoring and controlling by the implementation of IOT. So that people from another location can control manage and update the system. We can also use excess drained power to charge up street light batteries
