[Abstract]:The effective control of load temperature in large power network plays an important role in the safe transmission of power. A temperature control system for large power network load based on AT89C52-DS1820 is designed and implemented. The temperature of large power network load is monitored and controlled in real time. The temperature sensor DS1820 is used to measure, sample and convert the load temperature of power network. The test results are transmitted to AT89C52 single chip computer to compare the input temperature value with the set temperature value, and the temperature signal of load in large power network is controlled by thyristor trigger. Using anti-aliasing filter module to solve the power network load temperature signal frequency aliasing problem, through digital PID control algorithm to achieve power network load temperature control, the system temperature detection flow chart and program code are given. The experimental results show that the designed system can effectively control the load temperature of large power network and has high control accuracy.
