A protective relay plays a crucial role in the normal operation of a power system and the reliable supply of electrical power. The implementation of the modeling multi-functional hardware transformer protective relay based on a Field programmable gate array (FPGA) for a higher speed operation of protection is newly discussed in this paper. Taking the advantage of parallelism feature on FPGA, the proposed hardware transformer relay can process input signals of multi-channel with high speed, at the same time in real-time, and concurrently estimate and process different function protective logics. By using a single Altera CycloneⅢ EP3C40Q240CN8 and configuring different function protective relays, this relay allows us high-speed operation which is a basic demand of protection. This relay can operate within 1.1 cycle of the power frequency. The results demonstrate the operating speed and effectiveness of this protective relay for power transformers.

“…Recently new types of protective relay hardware are reported in the literature. In [20] a distance protective relay implementation in a field-programmable analog array (FPAA) is presented. This approach using a combination of FPAA and digital technologies has the potential to provide better performance than the present-day numerical relays; however, the use of analog blocks in the relay may have limitations on device size, switching noise, and sample-rate related bandwidth problems compared with digital technology.…”

The need for high-speed multi-function protective relays in both traditional transmission systems and the new emerging paradigm of the smart grid is growing. As a widely used protective scheme for transmission lines, a distance relay's high speed and reliable operation to clear faults is essential. This paper proposes a real-time low-latency hardware digital distance protective relay on the field programmable gate array (FPGA). Taking advantage of inherent hard-wired architecture of the FPGA, the proposed hardware distance relay design is paralleled and fully pipelined to achieve low latencies in various relay modules which are developed in textual VHDL language. This low-latency feature allows fast operating and data throughput so that the relay can handle high-frequency sampled data and reach higher computational efficiency. In addition, the parallelism and hardwired architecture of the FPGA makes the design more reliable in computation than the sequential software-based numeric relay. The FPGA-based distance relay can operate on both phasor-based signals and instantaneous signals with 2.09 and 0.35 latency respectively based on the clock frequency of 100 MHz. The hardware relay is tested in real-time by feeding it with generated faulted current and voltage data for typical faults and the relay response recorded. The results demonstrate the speed and effectiveness of the hardware distance relay.
