核电厂内仪器控制设备电磁干扰的研究

分析表明,核电厂与其他发电厂不同,自身安全是重要的保障,核电厂内各仪控设备之间和核电厂本身的电磁兼容性问题的显得尤为重要。通过建模、分析和试验,阐述核电厂仪控设备的干扰途径,根据仪控设备的电磁环境、电磁干扰耦合路径、电磁抗扰性评价因素,提出具体的电磁干扰防护措施,从而提升我国核电仪控产品的电磁安全性和可靠性。

Utilization of Data Communication according to the IEC61850 Standard for Nuclear Power Plant Electrical Equipment Testing

This paper deals with an integration of directly measured electrical parameters with data acquired by data communication from protections and terminals into an advanced monitoring system. Based on the periodic test, the authors of this paper present the possibility of an extended evaluation and more accurate analysis of transient and failure events. For periodical testing, as implemented during the commissioning of power plants in the Czech Republic, a monitoring system of electrical equipment has been used, to record the courses of important electrical parameters and thus, proving the proper functioning of complex technological systems in various operation modes. Data from monitoring system were used to prove the successful results of the test or as a base data for further analysis of failures. The monitoring system has proved itself as a very useful device also when recording unexpected failure events, the cause of which was very quickly and accurately detected by the follow-up analysis. Initially, only the voltage and current data from measuring transformers, analogue transducers and contact relays were used as input data for the monitoring system. After the implementation of new digital protection technology and controlling terminals with inner data recorder, the data from digital devices could be also utilized for the monitoring system.
