| 摘要: |
| 针对大型超高压变电站在运行条件下进行电气改造的要求，分析了变电站需要进行改造的主要原因及其电气改造过程中应遵循的相关规则；在此基础上，通过对大量超高压变电站改造实例的对比与分析，提出了超高压变电站在运行方式下进行电气改造的可行性方案。并以上海电网若干大型变电站的改造工程为例，介绍了利用该可行性方案对变电站双母线带旁路、双母线单分段带双旁路2种早期典型接线方式改造为双母线双分段接线的具体措施。 |

| Abstract: |
| The main reasons and related rules are analyzed for the electrical equipment reconstruction of large EHV（Extra-High-Voltage） substation under operation and the feasible strategy of substation reconstruction under operation is proposed based on the comparison and analysis of plentiful reconstruction practices. With several large substation reconstruction projects of Shanghai power grid as examples，the concrete measures in implementing the reconstruction strategy to transform two typical early connection modes，the double-bus with bypass and the double-bus single-section with double-bypass，into the connection mode of double-bus double-section are introduced. |
