Abstract：Static var generator（SVG）can governance power quality，energy conservation and reduce

consumption，furthermore it is an energy consumption product.The reasonable evaluation of the energy saving of

the device has become an urgent problem to be solved. The power saving measurement technology of products was

studied，and it was found that the existing power saving verification methods are not test methods. Because the field conditions are not unified，the verification results are not comparable. They can not be the data support of energy saving evaluation. At present，there is no set of effective testing methods in the field of inspection and testing that can be used for the power saving measurement of products in third-party testing laboratories，which makes both the testing work and energy saving evaluation work cannot be carried out.In order to make up for the above proposed detection technology gap，the innovative test method of design simulation resistance was proposed，so as to help complete the power saving measurement work. And a test platform was set up in the laboratory，to verify the feasibility and correctness of the method，and to assess the dispersion of the measurement results. The final conclusion is that the proposed method can be used for the third-party laboratory to complete the power saving measurement，flexible and controllable test conditions，can meet the requirements of various working conditions of the manufacturer，and the measurement results are comparable，can become the data support of energy saving evaluation，promote product iteration and update，and promote the progress of the industry.
