As the frequency of the network is constantly changing, in frequency tracking, the network frequency is given as a given value of frequency, and the switching switch S1 (hardware or software) in Figure 2, 3. 2, (hardware or software) is cut from upper to lower. The input and removal of frequency tracking function are usually done without manual intervention, and the electronic controller is automatically completed according to preset logic.. 

 

The hydraulic turbine regulation is essentially the speed regulation. The device for this adjustment is called the turbine speed governor. It is based on the deviation of the rotational speed of the unit to realize the adjustment of the guide leaf opening.. 

 

   At the main interface, press the numeric key "1" to enter the setup interface. The parameters need to be set are numbered and circumference. For the speed and way, there are different results.    In the former speed governor, the opening control mode is usually used, that is, the Y of the relay can be controlled by the opening of a given Y. In order to interface with the computer governor control systems better so that the upper computer can control the unit directly according to the electric power, the power control mode is generally added in the microcomputer governor. In actual operation, power control mode or opening control mode can only be chosen by two. 

 

     Speed limiter safety tong test is an important test for vehicle acceptance inspection and periodical inspection for speed limiter manufacturers. But what should we pay attention to when we do this experiment and do the experiment? For some newly established peers, there may be many questions. Today, the little rookie is going to share with you some personal experiences of this experiment. 

 

In 1868, the regulator, published by Maxwell, first described the motion state of the governor by differential equations. He derived the differential equation of the regulator and linearized it near the equilibrium point. It was pointed out that the stability of the root of the characteristic equation depends on the negative real part of the root of the characteristic equation.
