Design Of Relay Protection Setting Calculation System Of Power Plant

With the development of technology in the modern grid security protection, the relay setting calculation is the most important and most basic work. Therefore, it is very important to ensure safe and stable operation of power plants by a reasonable relay setting calculation. In this paper, by the actual situation of power plant, developed a suitable thermal power plant relay setting calculation system. Through this system, the staff can carry out the design of relay setting calculation and management of relevant data.The purpose of this paper is to design a system to autocomplete the work of relay setting calculations of the Power Plant. So that the staff can not do the heavy work of setting calculation, and reduce the errors caused by manual calculation, and the loss caused by failure. With a modular ideas, according to the function of the system, the system is divided into a drawing module, fault calculation module, setting calculation module and system management module.Firstly, learn the principles of power plant relay setting calculation. Then on this basis, design the overall structure and function of each module of this system, and use C # development tools and SQL database function to realize the function of each modules. Finally, test and analysis he function of system. The final test results show that the system can quickly and accurately to setting calculation, and reduce the workload of staff, the system has an important application value of oil thermal power plant safe and stable operation, reducing losses due to failure caused...
