Research And Development Of The Control System For The Power System Short-circuit Test-bench

There will be all kinds of malfunctions during the running process of power system. But the most frequent and harmful malfunction is the short circuit Short circuit malfunction can bring serious damage to industry and agriculture's production and people's life. By researching of the malfunctions of the short circuit, we can analyze the mechanism of it and adopt some ways to prevent the occurrence of the short circuit or make the harm of the malfunctions of the short circuit to the smallest.The power system short circuit test bench is the important part of the dynamic simulation lab which is one of the "211" project items of our university. So, it's important to study and to develop the control system of the power system short circuit test bench.Firstly, the thesis studies the characteristic and the key of the design of the control system of short circuit test bench.Secondly, we discuss the different ways to control the initial fault current angle, and give some different design projects based on PC. By analyzing the excellence and the shortcoming of all the design projects, we select the best design project which is that the system be controlled by two computers.Lastly, we give the principal technique and theory about the design of the hardware and application software in this system.
