Abstract

The invention discloses an ultra high voltage direct current (UHVDC) transmission engineering station system debugging method. Through carrying out calculating, a sequential operation test, a last trip test, a commutation bus charging and power outage test, an alternating current filter group and capacitor group charging and power outage test, a test of switching performed by a converter transformer instead of a converter and a charged test, an open circuit test and a secondary equipment anti-interference test to the engineering station, station system debugging steps of the UHVDC transmission engineering are clearly provided, work tasks and test projects in each stage are provided and the test projects are arranged scientifically and reasonably. Simultaneously, test contents of each kind of the test projects are provided in the invention. Calculation and research are performed to various kinds of converter station system debugging operation modes based on fully investigation of the equipment and the system. By using an extra-high-voltage change-rheological station debugging scheme, instructiveness and operability of the debugging scheme to engineering enforcement can be greatly raised, test projects listed in the debugging scheme can be guaranteed to be complete, a test sequence is clear and a test mode is safe.

Description

Technical field: [0001] The invention relates to the field of high-voltage direct current transmission, in particular to a system debugging method for an ultra-high voltage direct current transmission engineering station. Background technique: [0002] In today's society, the UHV DC transmission system has many advantages in high-power long-distance transmission and asynchronous networking, such as: strong transmission capacity, high transmission efficiency, long transmission distance, large transmission capacity, flexible control and convenient scheduling. Therefore, the application of UHVDC transmission system is becoming more and more extensive. Its project has become the focus of investment and operation. However, due to the large number of UHV DC transmission system equipment and the complexity of the system, before the end-to-end transmission and commissioning of the system, the UHV DC engineering station system must be debugged, and the reliability of each converter ...
