at no load is termed as asynchronous condenser. To improve the power factor, a synchronous condenser is connected in parallel to the load. It provides leading current that partially neutralizes the reactive power and improves the power factor.Fig. 3.17provides a diagram of a synchronous condenser...
Using a synchronous condenser has a number of advantages: • By changing the excitation of the synchronous condenser, stepless export and import of reactive power are possible (capacitive and inductive power). • By varying the amount and direction (import/export) of rea...
Eq. (3.75) of a synchronous motor can be represented by the phasor diagram as shown in Fig. 3.57. The phase angle δ between the stator voltage Vs and the excitation voltage Ef is an important factor of power transfer and stability in synchronous machines and is usually termed the power an...

2.With synchronous condenser: Now suppose that a synchronous condenser taking a leading current Im is connected at the receiving end of the line. The vector diagram of the circuit becomes as shown in Fig. 15.13. Note that since Im and Iq are in direct opposition and that Im must be ...

The block diagram shows the drive electronics associated with a low voltage (12 V DC) synchronous motor. These motors have aposition sensorintegrated within the motor, which provides a low-level signal with a frequency proportional to the speed of rotation of the motor. ...
This method does not require any additional controller and the synchronous machine can be operated as a synchronous condenser to control the reactive power in distribution systems and/or operate as a motor or generator set. However, its compensation characteristics depend on zero-sequence impedance of...
motor synchronous condenser control system of the present invention. It illustrates the present invention as applied to a single turbogenerator set 245 shown in the phantom box in FIG. 6. The turbogenerator set 245 generally comprises what is illustrated in the functional block diagram of FIG. 2...
(in this case, about 80% of a synchronous rotational number), the start switch33A is opened, the start condenser33is broken out from the circuit, and the synchronous induction motor2is operated only by the operation condenser32. Accordingly, at a time of operating the synchronous induction ...
