ZPL600

Overview:

    We design & install generator to generator or Generator to mains syncronisation systems.

    Multi set synchronising systems have certain advantages over a single large set installation:

    System flexibility
    Additional sets can be added as the demand rises. We can offer systems based on generators from 250-2200kVA with multiples of up to 32 units.

    Constant supply of power
    Should one set be down for maintenance then power is still available from the other sets in the system

    Lower fuel consumption and maintenance
    The load management system automatically calls up for generator(s) as the load rises and then drops set(s) out as the load falls. This means that set(s) are not running unnecessarily on low loads.

    The duty cycling facility within the system enables nomination of the lead set. This allows for equal usage between all the generators in the system.

    Ability to upgrade the system for a no break mains return
    By using G59 controllers. Synchronising & load share systems 250-2200kVA (Per Generator) up to 32 units can be Synchronised together.

    Our GES Synchset range generating sets can be supplied equipped with automatic synchronising & load share systems for controlling multiple generators.

    Standard set mounted DSE8610 system:
    With this system, each generator has a set mounted DSE8610 controller with integral synchronising and load share equipment, a circuit breaker with motor operator and a droop ct.

    A communications cable is the only inter set connection required and it is therefore simple to add further sets into the system.

    We can supply a separate common load panel to cater for the combined output of the generators.

    Alternative floorstanding suite system:
    With this system each generator is supplied without any set mounted instrumentation or controls. A fixed circuit breaker can be fitted to each set for cable protection if required. A droop ct is fitted to the alternator.

    The DSE8610 and motor operated circuit breaker are installed in a floor standing suite of control panels normally segregated into one section per generator and a separate adjacent load output section. The suite contains copper busbars from each generator to a common load take off/load output section.
    The communications cabling is also included within the suite. The suite can be supplied with either a common load ATS or common load MCCB/ACB section up to 6300 amps. Because of the inherent flexibility of the suit system we can incorporate additional equipment such as distribution breakers.

    General overview of GES Synchset synchronising systems
    The system is designed for Manual or Automatic starting of two or more 3-phase generating sets, with automatic synchronising, automatic load share & load management.

    The system can be left in full automatic mode so that when the start signal is received the system will start, synchronise and load share, until such time that the start signal is removed, whereby the generators will be held in a state of readiness for the next start request. During operation, the system will monitor the load demand and start/stop generators depending upon requirements.

    Generator starting
    There are two methods of starting the generating sets in the synchronising system:

    Manual Starting Automatic/Remote Starting

    Manual starting is achieved by the user physically starting the generator by use of the push buttons on the front of the control unit (Deep Sea 8610).


    Automatic starting will commence when a signal is applied to the controller, and cease when this signal is removed. All load demand parameters will be monitored by the controllers during the automated run period.

    Automatic Synchronising & load share

    Upon receipt of a remote start signal, all generators that are in automatic mode will enter the start sequence. The start sequence consists of:

    Start request received

    Delay on start timer

    Allows for any momentary

    dips in Mains voltage

    Fuel Solenoid Energise

    Start Solenoid Energise

    Generator Starts

    Load Demand/Load shedding and lead set priority nomination upon starting, there is a further safety on delay timer to allow the starting alarms (oil pressure, generator voltage, generator frequency etc.) to reach their lower threshold limits. Once these have been achieved, the generators will enter their loading sequence. The generator that is selected as the lead generator will automatically connect to the common bus, whereas the remaining generators will synchronise to the running generator.

    The system is designed to provide economical use of the available generating sets that are contained within the system with regard to equal load distribution and fuel consumption, and provides load demand/load shedding and lead set priority nomination.

    Following an automated start signal, all the sets in the system will start, synchronise and load share such that the full available generating set capacity is available to meet the potential load. After a pre-set time delay, the system will monitor the load, and if this is below a pre determined (programmable) level, will automatically remove one or more sets from the system in accordance with the lead set priority nomination. These will be held in readiness until such time as the load increases, whereby the dormant generators will be started, automatically synchronise to the running set(s) and connect to the load. Upon removal of the remote start input, the generators will disconnect from the common bus and enter the stop sequence.

    The following is an example of how the system works for three x 750 kva sets:

    The load demand system works by setting a minimum and maximum setting % in kW in each controller. These are adjustable through the whole range 0-100%.

    Basing the maximum level set to 90% and the minimum to 60%. Based on 750kVA sets (600kW) the levels would be:

    90% = 540kW

    60% = 360kW

    With one set on load as it reaches 540kW, the 2nd set will be called for. When the load then reaches 1080 kW the 3rd set will be called foAs the load decreases the system will monitor the total load, and if this falls below 720kW (2 x 360kW) the 3rd set will unload, open its breaker and stop. As the load continues to fall, should it go below 360 kW the 2nd set will unload, open its breaker and stop.

    On initial startup the system assumes the max kW level has been exceeded and the load will need to reduce below the min level before set(s) are dropped off.

    The priority duty generator is selected on the SCADA system, and all generators will synchronise to that generator. However, the system will automatically disconnect the priority generator should the load demand decrease, providing that the engine operating hours of the remaining generators is above the balance engine hours requirement.

    For instance, if the balance engine hours is set to 75 and one of the non-priority generators has an operating hour difference of 76 or more, to the priority generator, this generator will become the priority generator until such time as the engine operating hours are equal.
