摘要
介绍了西门子公司的SIMATIC S7-300 PLC控制系统的特点及硬件、软件组态。通过该系统实现了简单、可靠且高效的主变压器油水冷却器系统的控制,从而将变压器油温控制在合理运行范围内,保证了变压器的安全、稳定运行,延长了其使用寿命。
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.
