现场总线具有良好的开放性和可操作性,系统结构高度分散,现场设备高智能化和功能自治的特点。使用现场总线可以减少硬件数量与投资,降低安装费用,减少维修工作量,提高工作效率,提高系统的准确性和可靠性。现场总线在火电厂应用中虽然还存在一些问题有待完善,但随着电力体制改革的加速,火电厂信息化与管控一体化要求的日渐迫切,现场总线将成为我国火力发电厂改革创新的必然选择。 Fieldbus has a good openness and operability, the system structure is highly dispersed, high-intelligent field devices and functional autonomy features. The use of fieldbus can reduce the amount of hardware and investment, reduce installation costs, reduce maintenance workload, improve work efficiency, improve system accuracy and reliability. Although there are still some problems to be improved in the application of thermal power plant in the field bus, with the acceleration of power system reform, the integration of thermal power plant information and control increasingly urgent, fieldbus will become the inevitable choice of China’s thermal power plant reform and innovation .
