智能高压设备的电磁兼容性试验端口模型研究

Research on Electromagnetic Compatibility Test Technology of Smart High Voltage Equipment

智能高压设备是构建智能电网的核心设备,智能电子装置是高压设备智能化的基本单元,智能高压设备的电磁兼容性主要表现为智能电子装置的电磁兼容性。基于此观点,笔者引入试验端口概念,定义了智能电子装置的试验端口,给出了智能电子装置电磁兼容试验端口模型。从保证试验有效性角度总结了智能电子装置电磁兼容性试验四要素,据此讨论了实施型式试验和现场试验的条件。最后,将该端口模型与国家电网公司新发布的有关企业标准做了比较分析,从试验完整性角度探讨了完善试验项目的建议。

Smart high voltage equipment （SHVE） is a core device for constructing the smart grid and the intelligent electronic device（IED） is a basic unit of SHVE, so the electromagnetic compatibility （EMC） of lED reveals the SHVE-EMC. From this point, this paper defines IED-EMC test models based on test ports concept. Four factors are put forward in order to ensure the validity of the IED-EMC test, and a discussion about conditions between carrying out ~he type test and the site test is provided. Finally, a comparison between the IED-EMC test model and company standard of state grid corporation of China is done, followed a suggestion for perfecting the test items is given to guarantee the integrity of the IED-EMC test.
