摘　　要：随着人工智能的发展,智能化技术得到了广泛应用,继电保护作为电力系统的重要保护装置,其动作的灵敏性和对故障判断的正确性对系统的安全稳定运行具有重要影响。保护定值作为继电保护装置的重要参数,其整定值直接决定保护装置的性能,传统的参数整定对经验和历史数据的依赖性较高,无法实现保护定值优化配置。本文将智能化技术与继电保护相结合,提出了一种采用神经网络学习实现保护定值的整定和优化的方法,并通过对历史数据的处理和分析,建立了适应度函数并对不同定值的保护性能进行评估,从而实现继电保护定值优化配置。该方法适应性强且可扩展性好,有效提升了电力系统的稳定性,具有较好的应用前景和实用价值。With the development of artificial intelligence,intelligent technology has been widely applied.In power systems,relay protection serves as a crucial safety mechanism,where the sensitivity of its actions and the accuracy of fault diagnosis play a significant role in ensuring safe and stable system operation.The protection setting value,as an important parameter of relay protection device,directly determines the performance of the protection device.Traditional parameter setting relies heavily on experience and historical data,and cannot achieve optimized configuration of protection setting value.This article combines intelligent technology with relay protection and proposes a method for setting and optimizing protection settings using neural network learning.By processing and analyzing historical data,a fitness function is established and the protection performance of different settings is evaluated to achieve optimized configuration of relay protection settings.This method has strong adaptability and good scalability,effectively improving the stability of the power system,and has good application prospects and practical value.
