它是以水位作为水量平衡与否的操控目标，经过调整进水量的多少来到达进出平衡，将汽包水位保持在汽水别离界面最大的汽包中位线邻近，以进步锅炉的蒸发效率，确保出产安全。因为锅炉水位体系是一个设有自平衡才能的被控目标，作业中存在虚伪水位景象，实践运用中可依据情况选用水位单冲量、水位蒸汽量双冲量和水位、蒸汽量、给水量三冲量的操控体系。所谓三冲量调理体系即是把给水流量W，汽包水位H，蒸汽流量D三个变量经过运算后调理给水阀的调理体系。详细调理进程方框图如图2所示。

1、V/F操控及无速度向量操控。
2、发动转矩在2HZ时达150%。
3、主辅频迭加功用。
4、AVI/ACI设定，RS485通讯，脉冲输入频率操控(可选)。
5、内置PLC可16段速程序作业。
6、3段制止频率可有效避免共振。
7、操起器可外延。
8、摆频功用。
9、PID回馈操控。
10、刹车选用软件操控，可调整刹车准位及制动运用率。
11、硬件与软件滤波相联系，更佳的抗搅扰效果。
12、过电压、过电流、低电压、过负载约束、超载、过热等多种维护功用。
