基于电网云数据管理的电气设备大数据移动实验室及其应用研究
摘要：针对目前变电站设备试验作业过程中遇到的效率低下、智能化作业水平低、数据信息化应用水平不高等问题，研发了基于电网云数据管理的移动实验室平台。重点阐述了该移动实验室平台内嵌专家分析系统在结果判定上的理论过程，结合变压器差动保护动作后的现场实际应用案例，依据低电压短路阻抗法、电容量法、频率响应特性法、变比及直阻试验测试结果，说明该试验平台在现场实际应用时，内嵌专家分析系统分析变压器遭受短路冲击后引发绕组形变状况的可靠性。最后，根据返厂解体检查结果，进一步验证该平台在现场应用的有效性。
Abstract:Aiming at the problems of low efficiency, low level of intelligent operation and low level of data informatization application encountered in the current substation equipment test operation, a mobile laboratory platform based on grid cloud data management was developed. This paper focused on the theoretical process of the result judgment of the expert analysis system embedded in the mobile laboratory platform. Combined with the practical application cases of transformer differential protection after operation, according to the test results of low-voltage short-circuit impedance method, capacitance method, frequency response characteristic method, transformation ratio and direct resistance test, the reliability of the embedded expert analysis system to analyze the winding deformation caused by the short circuit impact of the transformer was illustrated. Finally, according to the results of the dismantling inspection after returning to the factory, the validity of the platform in the field application was further verified.
