| 摘要: |
| 为进一步实现对智能变电站改扩建工程的运维管控，提出了一种基于SCD比较的二次系统回路变更影响范围定位方法。通过比较改扩建前后SCD文件中一次系统描述部分，实现受影响的间隔区域定位。比较受影响间隔内二次装置CRC码，判别该二次装置是否受到波及。进一步比较受波及装置通信描述及关联信息描述部分，分别实现对改扩建工程前后二次系统实际物理链路及逻辑虚拟链路受波及部分的快速定位。最终以图形化建模的实现方式为基于SCD比较的二次系统回路变更影响范围定位方法的具体应用提供了有效手段。 |

| Abstract: |
| In order to achieve the management and control of smart substation operations, this paper proposes an impact range positioning method based on upgrading SCD in modification or extension project. According to comparing primary system specification description part in SCD file, the scope of influenced bays can be located. Then, it is judged whether the secondary device is affected or not by comparing IED’s CRC. To compare the affected IEDs’ communication description part and input description part, the influence scope of secondary system of physical link circuit and logical link circuit before and after modification and extension can be located respectively fast. At last, it provides the graphically modeling tools to realize this effective means of positioning the influence scope in secondary circuit by upgrading SCD. |
