Abstract: The features and hardware and software configurations of the SIMATIC S7-300 PLC control system produced by Siemens were introduced. The simple, reliable and higheffective control of water cooling system for main transformer oil was realized by using of the SIMATIC S7-300 PLC control system. The temperature of the main transformer oil was controlled in rational operation range, and the safety and stable operation of the main transformer was ensured, and its service life was extended.
