补充资料：发电厂给煤机变频调速系统
发电厂给煤机是电厂制粉系统中重要组成部分，是电厂重要的辅助动力设备，其主要任务是为制粉系统磨煤机提供原料。
制粉系统工艺流程图
系统功能框图
根据给煤机稳定运行的重要性，采用冗余控制系统。
变频调速系统电气回路图
电气回路由空气开关、接触器、中间继电器、电流互感器、端子排、电缆等组成。变频器用双回路电源供电，当一路电源工作，则另一路电源作备用电源处于热备用状态，当工作电源失电或发生故障时，自动投入备用电源。
优点：实现软启动，启动电流小且平稳，减少对电网和设备的冲击。能连续无级调节给煤机的速度。给煤机长期运行在30Hz，节约能源。具有多种保护功能，易于维护、维修，符合工厂自动化发展趋势。
