Research on Load Tap Changer Based on Power Electronic Switch

为进一步提升电网电压运行稳定性,本次基于调压的角度,以电力电子开关为核心模块设计调压模块。在设计过程中,结合电力电子开关应用的可行性,分别从硬件结构和运行逻辑两方面着手,详细地探讨了基于电力电子开关的有载调压技术模式,并对本次设计的技术模式进行了模拟测试。测试结果表明,输出电压幅值均达到了预期目标,且并未影响输出电压波形的连续性,证明本次设计取得了初步成功。

The improvement of power grid voltage stability can be further optimized through a voltage regulation perspective.This can be achieved by designing a voltage regulation module that centers around the use of power electronic switches as the core module.In order to ensure the practical application of the power electronic switch,this module is designed with on load voltage regulation techniques,which are discussed in detail based on hardware structure and operation logic considerations.The performance of the voltage regulation module is tested through simulation,and the results indicate that the expected goal for the output voltage amplitude has been achieved while maintaining the continuity of the output voltage waveform.These preliminary results prove that this design approach has been successful.
