Utilities produce and supply products following local requirements and with the synchronizations which connect subscribers. Harmonics is a power efficiency/quality variable caused by electronic devices that domestic and industrial consumers use. The famous IEEE Standard 519 is maintained to calculate harmonic limits, which ensures power efficiency. In a standard power system, currents and voltages generate pure sine wave signals during regular operations. As harmonics influence the power system, they cause interference in the sine wave signals. So, the best practice method should be used to resolve the harmonics issue. One of the problem-solving techniques of harmonics is the measurement and reduction of harmonics detection, and it uses Fast Fourier Transform (FFT). Therefore, power output should assess in a peer-to-peer Blockchain scheme by measuring and minimizing harmonics detection. This paper uses a Shunt Active Power Filter (SHAPF). It describes the simulation analysis and reduction of harmonics detection in a peer-to-peer interconnected 3-phase power system with the help of an FFT algorithm. This research was carried out to assess the efficiency of the AC signal by collecting, processing, and evaluating power data. Using the shunt active filter, the proposed design outperformed the traditional methods for both six and twelve pulse rectifiers, achieving total harmonic distortion (THD) of only 1.42% and 0.92%, respectively.

公用事业公司按照当地要求生产和供应产品，并与用户保持同步。谐波是由家庭和工业消费者使用的电子设备引起的电源效率/质量变量。维护著名的 IEEE 标准 519 来计算谐波限制，从而确保电源效率。在标准电力系统中，电流和电压在正常运行期间产生纯正弦波信号。由于谐波影响电力系统，因此会对正弦波信号造成干扰。因此，应使用最佳实践方法来解决谐波问题。解决谐波问题的技术之一是谐波检测的测量和减少，它使用快速傅里叶变换（FFT）。因此，应通过测量和最小化谐波检测来在点对点区块链方案中评估功率输出。本文使用并联有源电力滤波器（SHAPF）。它描述了借助 FFT 算法对点对点互连三相电力系统中的谐波检测进行仿真分析和减少。本研究旨在通过收集、处理和评估功率数据来评估交流信号的效率。使用并联有源滤波器，所提出的设计优于六脉冲整流器和十二脉冲整流器的传统方法，总谐波失真 (THD) 分别仅为 1.42% 和 0.92%。
