A power system network generates, distributes and transmits the electricity. The reliable, as well as safe power systems, are very significant for successful operation. However, various losses and faults occur in power system which prevents the power system to work efficiently and also causes various damages. Overcurrent is a very critical fault as it results in extreme production of heat, and the possibility of fire or device damage, if not tripped timely. In order to protect the equipment from overcurrent, the overcurrent relays were designed. In the existing system, the Inverse Definite Minimum Time (IDMT) over-current relay was used for purpose of over-current protection. However, it consists of various drawbacks such as, they take more time to trip which can lead to damage in equipments. Also, the IDMT over-current relay faces the issue of fault severity variation. Thus, in order to overcome the previous issues, the PID based relay is designed in the proposed work which will perform fast tripping and perform well for different faulty conditions. In this paper, the simulation has been performed to ensure the efficiency of the proposed approach over the conventional one.

Traditional overload protection methods usually use either breakers or converters, focused on the side of power supply. However, these schemes may suffer from a slow response time or load dependence. Particularly, the facility may not be able to remain as a regular working condition when an overload occurs. To resolve this problem, the proposed feedbackcontrolling resonant switching algorithm aims to provide an expected load constant current to protect the load from overload without sacrifice for a normal load operation. On the basis of a negative feedback-control mechanism, the proposed model can detect the load current and thus generate an appropriate switch signal fast and accurately. The switch open period is decided by the model parameters and load current, and it can be set in advance by the timer. On the other hand, the switch closed period is determined by the expected load current that is independent on the load size. The switching acts at the resonant zero-voltage point, so that no power is consumed during the switching action. The performance simulation with DC 28 V supply confirms that the proposed model can maintain a predefined load constant current for an overload protection effectively.
