一种综自变电站故障录波器技术改造方法研究

Research on a Technical Transformation Method of Fault Recorder in Comprehensive Automatic Substation

故障录波装置在变电站内的作用逐渐提高,其功能及改造需满足相应的规范和反措要求。老旧变电站的故障录波器很难满足新规范要求,这主要是由于保护装置功能不足导致的。为更好地实现故障录波装置的功能,采用装置软报文形式实现各个接点的接入,便于故障时更好地与硬接点配合使用,更加清晰可靠地实现故障还原,此外还对故障录波装置的故障分析计算进行了更加人性化的补充。

The role of the fault recorder in the substation is gradually increasing,and the requirements for its function and transformation must meet the corresponding specifications and countermeasures.However,it is difficult for the fault recorder of the old substation to meet the requirements of the new specification,which is mainly caused by the insufficient function of the protection device.In order to better realize the function of the fault recording device and implement it in accordance with the specification,this article adopts the device soft message form to realize the access of each contact,which is convenient for better use with the hard contact in the event of a fault,so as to achieve a clearer and more reliable fault recovery.Secondly,a more humane supplement to the fault analysis and calculation of the fault recorder.
