Two scientific and technological achievements of Gansu Electric Power Company passed the provincial appraisal

The two scientific and technological achievements of “Relay Protection Setting Calculation and Data Management System” and “Gansu Power Office Automation System” developed by Gansu Electric Power Co., Ltd. passed the results appraisal organized by the Science and Technology Department of Gansu Province on December 5th. Experts believe that: Its level has reached the domestic leading level.
"Gansu Power Office Automation System" is based on the Gansu Electric Power Wide Area Network, supplemented by dialing, and it has realized the relationship between the Gansu Electric Power Company and each power plant and its subordinate units (including the subordinate units of the subordinate units and the charge of the Agricultural Power County Bureau). The electronic document circulation also realized the exchange of electronic documents with the provincial government, State Grid Corporation of China, and the Northwest Power Grid Corporation, which greatly improved the speed of transceiving texts and the efficiency of office work. The system has a large coverage and is highly practical. The whole process of receiving and sending texts can be tracked, seamlessly integrated with Word, and the function of modifying traces can be retained, and a document format conforming to the national standard can be automatically generated. In particular, the red-headed documents and the automatic processing functions of the electronic seals provided in the system are innovative in similar projects.
"Relay protection setting calculation and data management system" is a comprehensive professional project developed for the calculation of relay protection setting in Gansu power grid, which is always under manual calculation or application of fault calculation software to assist in calculation, heavy workload, and prone to mistakes. Software system. The system adopts the method of equal value area reduction in the algorithm, which makes the calculation of the maximum value of the fault amount and the branch coefficient of the grid more accurate, the calculation speed is faster, the algorithm principle is advanced, and the calculation result is reliable. It provides the relay protection setting calculation and data management. A new platform. Experts of the appraisal committee unanimously held that the system is well-designed, advanced in algorithm, and powerful in functionality. It has made breakthroughs in the calculation of the maximum value of power grid failures and branch factors, and is at the leading level in China.
The two achievements are key scientific and technological projects determined by the provincial power company. They were promoted and applied in the provincial company system in 2000 and 2003 respectively, and achieved good application results.
