4. Need for reactive Power Compensation Voltage variation at a node is indication of the unbalance between reactive power generated & consumed by load. P = (V1V2)sinδ / X, Q = V1(V1 – V2cosδ) / X If reactive power generated is greater than consumed by the node, the voltage goes up & vice versa. Lack of reactive power can cause voltage

Reactive Power Compensation. A low value of power factor requires large reactive power and this affects the voltage level. Hence in order to compensate for the reactive power, the power factor of the system must be improved. Thus, the methods for reactive power compensation are nothing but the methods by which poor power factors can be improved

Reactive power inefficiencies are a well-known issue in power systems, and many advanced and developing countries have addressed this through private investments in technologies like Static VAR Compensators (SVCs) and capacitor banks. The lack of sufficient action in Kazakhstan can be attributed to artificially low electricity prices resulting
The circuit diagram of compensation capacitors and peripheral hardware in the implemented hybrid reactive power compensation system is also given in Fig. 7. As can be seen in this figure, there are six single-phase and two three-phase capacitors. Rated powers of each capacitor are also shown in the same figure.
Once the problems of reactive power generation, transmission and distribution have been exposed, we will proceed to describe the actions that the customers can adopt in order to avoid or minimize the corresponding penalization in the electricity bill. These actions are covered by the denomination ‘reactive power compensation’.
In the first case, assuming that only capacitors exist in the compensation system, classical reactive power compensation was applied. In the second case, hybrid compensation was done by using hybrid reactive power system with synchronous motor, which is the subject and purpose of this study.
The controller, after some calculations, decides on the capacitor stages closest to these powers and activates them. However, after the capacitors are switched on/off, unlike conventional capacitor switched compensation systems, the reactive powers drawn from each phase of the grid must be of the same type.
Through the logic drive circuit, pulse width modulation circuit, zero point detection circuit and power factor detection circuit, the on-off of the self-turning off device in the switch circuit was controlled to control the charging and discharging voltage of the compensation capacitor, and then the capacitor compensation current was controlled.
Therefore, taking into consideration the basic Equation 1, we can conclude that, for a certain apparent power S, the higher the reactive power (Q) to be generated (in order to the supplied to the customers), the lower the active power (P) that the generator can produce. In other words, the generation of Q limits the capacity of generating P.
