| 摘要: |
| 针对目前电力行业在主变带负荷相量测试普遍采用手工绘制相量图，存在着绘图效率低、准确性差、作图不规范等缺点，提出了一种利用Visual C++语言编制可视化界面相量测试软件的新方法。具体阐述了该方法的实施步骤，包括模态对话框建立、测试方式选择界面、原始测试数据输入界面、相量图绘制界面，主变三相差动电流计算。该方法能够快速绘制出相量图、准确计算出主变差动保护差动电流，并实现了原始测试数据的保存及测试报告单的打印功能，满足主变相量测试工作需要。 |

| Abstract: |
| Currently, the transformer phasor diagram of on-load phasor test is generally drawn by hand in electricity industry, which has some defects, such as low efficiency of drawing, bad accuracy and non-standards drawing, etc. According to those defects, this paper presents a new method of visual interface software for phasor test, which is compiled by Visual C++ language. The implementing procedure is explained, including modal dialog box establishment, test methods selection interface, original test data input interface, phasor diagram drawing interface and three phase differential currents calculation of transformer. This method can draw phasor diagram quickly and calculate the differential current of main transformer differential protection accurately, what's more, it achieves the original test data preservation and the print function of the test report, meeting the requirements of phasor test work. |
