Thyristor Switched Capacitor Panel

In this type of system, Thristor's are used for switching of capacitors.. This is usually used in variable load conditions.

Automatic power factor correction is typical for large electrical systems with fluctuating load where it is common to connect number of capacitors to main power distribution station or substation. The capacitors are controlled by controller which continuously monitors the relative power demand. The relay connects or disconnects the capacitors to compensate for actual reactive power of the total load and reduce overall demand supply. Thyristors are used to switch the capacitors On and Off in the system.

Power Quality Analyzing

We have 10 years experience of carrying out Network Power Quality study in various sectors like Auto mobile Industries, Steel Industries, Sugar Industries, IT Parks, Hospitals, Cement Industries, Textile Industries and Tyre Industries, Chemical Industries, Hotels etc. We have equipped with tools like FLUKE-435 and KRYKARD ALM Power Quality Analyzer for Network study& separate team of engineers for this activity. The power analyzer is able to record various power system parameters like Voltage, Current, Active power, Reactive Power, Apparent Power, Power Factor, Current and Voltage Harmonics up to 50th order in numerical as well as graphical format. Software’s like MATLAB & SKM we are using for simulation & offering correct solution to improve power quality of electrical system for various applications. Improving power quality can bring significant financial benefits. • • • • • • •

  • Poor power quality can damage sensitive equipment.
  • Poor power quality can lower productivity and also drive up energy costs.
  • Poor power quality can cause increased expenditure on electrical assets when plant or building expansion is necessary.
  • Poor power quality can impair the safety of electrical installations.
  • Harmonic distortion and voltage fluctuations.
  • Low power factor—this can increase electricity costs through maximum demand charges.
  • Power electronic loads (variable speed drives, welders, CNC machines, etc).
  • Inadequate wiring plan, and undersized circuits.

Reactive Power Compensation Design

We offers reactive power compensations designs. Reactive power compensation is defined as the management of reactive power to improve the performance of alternating-current (ac) power systems. In general, the problem of reactive power compensation is related to load and voltage support. In load support the objectives are to increase the value of the system power factor, to balance the real power drawn from the ac supply, to enhance voltage regulation, and to eliminate current harmonic components produced by large and fluctuating nonlinear industrial loads. Voltage support is generally required to reduce voltage fluctuation at a given terminal of a transmission line. Reactive power compensation in transmission systems also improves the stability of the ac system by increasing the maximum active power that can be transmitted.

Schemes for Reactive power compensation

1) Dynamic Power Factor Correction Panels.

Very fast / real time response to changing loads. Response time in micro seconds. Due to very fast capacitor bank operation maintaining PF close to unity is possible. Contractor operated APFC panel respond to changing loads in a sluggish / delayed manner. Due to slow response these panels are unable to maintain PF close to unity.

  • Welding Machine Application
  • Automobile Industry
  • DC Drive Applications

2) Contactor Based APFC Panels

Reactive Power compensation system is designed to work automatically on LT power supply to measure , display & connect, disconnect the required capacitor banks through Capacitor Duty contactor with protection of MCB / HRC Fuses & series reactors to each bank to achieve the set Target power factor.

  • Automobile Industries, Cement Industries, Metal Industries.
  • Chemical & Fertilizer Plant, Pharmaceutical Industries.
  • Hospitals, Malls, Banks, IT Parks, Commercial Complexes.
  • Crushers.
