Problems solved by technology
[0004] To sum up, at present, in the whole process of power plant relay protection setting calculation, the transition between the three main links still needs manual intervention, and there is no effective method to organically integrate the above three links. Combination, at the same time, when a fault occurs, it does not have the function of quick adjustment and simulation, which is not conducive to the rapid solution of the problem

The invention discloses a relay protection setting calculation method and system for a power plant. The method comprises the steps: displaying all electrical apparatus elements and connection lines through basic primitive design, outputting an operation result of an electrical apparatus to circuit design, connecting a database, carrying out calculation and protection on the setting value of the electrical apparatus through the protection of a high-voltage power supply system, acquiring user data, querying and storing the user data, performing local design by using a built-in custom calculationmodule, improving the fault solving efficiency, performing online simulation by locally simulating the protection and database connected with a high-voltage power supply system, and applying the qualified data to the whole setting process to realize the setting calculation of the power plant relay protection. According to the invention, the method for realizing relay protection setting calculation of the power plant depends on a system for relay protection setting calculation of the power plant, the system comprises protection of a high-voltage power supply system, basic primitive design, user data and local simulation, and the method is realized.
Description
technical field [0001] The invention relates to the technical field of power plant relay protection setting calculation, in particular to a power plant relay protection setting calculation method and system. Background technique [0002] Relay protection is an indispensable and important part in the power system, which is directly related to the safety of power equipment and the stable operation of the power system. The setting calculation of relay protection plays an important and basic role in the safe and stable operation of power plants and power systems. In order to ensure the safe and stable operation of power plants, various relay protections must form an organic whole and cooperate with each other to form a tight system. Improving the automation level of relay protection fixed value calculation and improving the accuracy and precision of calculation results can provide strong technical support for building a strong power grid. [0003] The process of completing the...
