摘要:
      抽能型电抗器由于其结构不同于电抗器和变压器,抽能绕组匝间故障如何快速保护没有得到共识,且工程应用中也少。基于三相抽能绕组三角形接法的特点提出配置环流过流作为动作元件,采用电抗器侧零序过压或零序过流作为闭锁元件,实现抽能绕组匝间故障的快速保护,并对抽能绕组匝间故障下的环流进行分析;通过对量化测试验证物理模型的有效性,提出抽能绕组匝间保护的动模测试方案并进行测试,测试结果验证保护逻辑的合理性。
Abstract:
      Because the structure of energy-extraction reactor is different from that of reactor and transformer ,there is no consensus on how to quickly protect the inter-turn fault of the pumped windings and it sengineering applications are rare.According to the characteristics anlysis of triangular connection of three-phase pumped windings, the circulating overcurrent is set as the action element,the zero-sequence overvoltage or the zero-sequence overcurrent at reactor side acts as the locking element,which can realize the fast protection of inter-turn fault in pumped windings,and the circulating overcurrent of the fault is analyzed.Finally,the effectiveness of physical model is varified by quantitative testing, a dynamic simulation testing scheme for inter-turn protection of pumped windings is proposed and the test results verify the rationality of the protection logic.
