Abstract On the basis of the research on the abnormal judgment and processing logic IDNC neutral bus DC current in Yanhuai UHVDC project at present, the abnormal working conditions of the current system are analyzed, and the anomaly judgment and processing logic IDNC UHVDC transmission system is improved. The RT-LAB real-time simulation model based on Yanhuai UHV project is built. The test results are reasonable and effective. At last, the abnormal judgment and processing logic IDNC has been applied to the UHV system in operation, and achieved good economic and social effects.
