AUTOMATIC CO-GENERATION MANAGEMENT SYSTEM

Product catalog summary

Overview: The document describes the KSQ304E, a digitally controlled automatic co-generation management system designed for single generator systems. It is suitable for peak-shaving and can be used with any GenSet starter alongside Megacon's protective guards and controllers.

Specifications: The system operates at various voltages (100-120, 200-240, 380-415, or 440-460VAC) and frequencies (40-70Hz). It features adjustable parameters such as frequency difference, voltage differential, circuit breaker closing time, frequency reference, pulse rate, pulse width, and load trim. The system is designed to handle temperatures from -20 to +70ºC and has a front protection rating of IP54, with an optional upgrade to IP65.

Synchronising Modes: The KSQ304E offers three synchronising modes: LEAD, LAG, and NEUTRAL. LEAD is the standard mode, where the synchronising relay closes when the incomer's frequency is slightly higher than the bus frequency. This prevents reverse power conditions post-synchronisation.

Speed Control: The system uses a proportional/integral (P/I) characteristic for speed control, with a dynamically controlled dead zone. The raise/lower relays adjust the fuel regulator or an interfacing electronic potentiometer, with adjustable pulse width and rate.

Operational Modes: The KSQ304E operates in several modes:

Frequency Control Mode: Activated after the GenSet starter receives a START command.
Synchronising Mode: Automatically synchronises the generator to the mains.
Load Control Mode: Controls the slope of generator loading and engine speed to match the set kW export level.
Unload Generator/Breaker Trip Mode: Reduces engine speed and offloads the generator load at a controlled slope, eventually tripping the breaker.

Compliance: The unit complies with IEC60092-504 and relevant environmental and EMC tests specified in IEC60068/60092 and IEC61000/60533, meeting the requirements of major Classification Societies.

Applications: The KSQ304E is suitable for various applications, including those in Norway, the UK, and Denmark. It is designed for continuous improvement, and specifications may vary.

User settable limits on unit rear for frequency sync. difference, voltage differential, frequency reference, circuit breaker closing time, fuel regulator pulse width and pulse rate, load trim reference when paralleled to mains. Note thatthe kW load signal input needs to be calibrated to be 0-110%of generator nominal load.

LEAD (incomer faster than bus), LAG (incomer slower than bus), . (bi-directional) LEAD is the standard mode. The synchronising relay will then close when the frequency of the incomer is slightly HIGHER than the bus frequency. This avoids a non-stabilised incomer entering reverse power condition after synchronisation. The rotary LED display indicates the incomer's speed relative to the bus, and is lit during frequency mode if the difference between the systems does not exceeds 5Hz. During all modes the UP/DOWN arrows indicate the pulses from the raise/lower speed relays. Speed control The raise/lower relays pulse the fuel regulator or an interfacing MXR845electronicpotentiometer. Pulse width and rate can be adjusted to suit the dynamic response of any fuel regulator. The speed control has a P/I (proportional/integral) characteristic with a dynamically controlled dead zone. mCQQCOn Norway - UK
