Control Panels Green. Bug Energy. Introduction. Green. Bug Energy has developed the following Fixed Speed Control Panels for our grid tied Archimedes screw generator systems. Our Fixed Speed Induction Generator Controls Panels are designed for interconnection with the utility for either net metering or revenue producing applications such as Feed in Tariff programs. Panels are available in various combinations of 1 phase, 3 phase, 4. SEL 5. 47 and SEL 7. GT protection schemes. To locate members in other locations, use the dropdown menu boxes.

Generator power out values from 1 to 1. W single phase and 1 to 2. W three phase. All panels use 3 phase induction motors as a grid connected Induction Generator to produce either 1 or 3 phase power. Single phase induction motors cannot be used as generators. Three phase motors used to produce single phase power use run capacitors arranged to put the generator in a balanced condition. Each of the panels ships with 1 a single line drawing and component list and 2 a Philosophy and Control Document. To find the panel you need faster, this is the way to interpret the SKU First number is the phase, either 1 or 3 and should match your service available Second number is the voltage of the control panel, either 4. Third number is the Maximum Induction Generator Nameplate Amperage that the panel is designed for. Fourth number is the protection relay the control panel uses, either SEL5. SEL7. 00. GT. The SEL7. GT provides additional protective features. Fifth number applies to three phase panels only is Greenbugs name for the protection scheme given the SEL relay that is being used. MP indicates voltage is being measured on two of the three phases using two current transformers. DW indicates voltage is being measured on all three of the three phases using two current transformers.

A Bypass Contactor is utilized so that power is not going through the SCRs all the time. The SCRs allow for soft starting of the generator, but after startup power is routed through the Bypass Contactor instead of through the SCRs because the SCRs consume a lot of power and they also produce a lot of heat. To determine which control panel you need Determine your generator size in k. W or HPNext Determine your existing service size phasevoltagek. VA Generally, you want to use the biggest service voltage you can because it makes things cheaper, but if you have a service already you will want to use that service whatever phase and voltage it is as it will likely be cheaper than installing a new service. However the generator k. Web oficial de la Universidade da Corua. Enlaces a centros, departamentos, servicios, planes de estudios. The HP67 was a magnetic cardprogrammable handheld calculator, introduced by HewlettPackard in 1976 at an MSRP of 450. A desktop version with builtin thermal. W size will likely have to be 8. VA size or less. If its not the existing servicetransformer may have to be upgraded. For example if you have a 1. Rise Of Nations 2 Rise Of Legends Highly Compressed Game. VA service total on three phases, the maximum system size the utility will likely let you connect is 8. W. If you have a 1. W system you want to connect, this would require upgrading of your transformer. Next Identify the chart below that corresponds to your service phase, either single or three phase. Next Identify on that chart the panel types that are built for your service voltage. There may be several. Ie Panel type F and panel type M are both built for 5. Next, for the Panel types identified above, search down the list of panels in the Maximum IG Output k. W or HP column for the panel that just exceeds your generator size. If you only found one control panel that fits, this is your only option. However, if you found several control panels, then next decide which protection level you prefer or need. Now that youve selected your control panel, you want to ensure that when you purchase your generator, that the voltage of the generator is at least as high as the service voltage. Ie if your service voltage is 5. Also when selecting your generator, you must check to ensure its maximum nameplate amperage does not exceed the Maximum IG Nameplate Amperage of the control panel you selected. If it does, you need to select either a different control panel or different motor. This is the reason for Note 2 on the panel lists. It is possible that motors other than the motors identified in Note 2 may have different maximum nameplate amperage ratings than the motors identified, and the control panels are built only to accommodate the certain maximum IG nameplate amperage identified on the sheets. Features and Benefits. Pre engineered panels. Decrease project cost and risk by using panels that have already been designed and are widely accepted. Easy selection based on generator nameplate. Simple selection charts allow an end user to select the appropriate panel based on their requirements. Panels cover wide range of single and three phase applications. Panels cover widest range of standard voltages in North American 6. Hz environment. Automatic Restarting. Generator will restart on its own with no need to human intervention. Choice of SEL 5. 47 or 7. GT protection schemes. Allows the user to select the most cost effective option for their project. Soft Starting. Ensures there is no shock to the distribution system in the event of a hard start, a problem often associated with fix bladed wind turbines. Panel Meter display Volts, Amps, Frequency, Active Power and Apparent Power Reactive Power, Active Energy, Reactive Energy, Power Factor, Amp Demand, Apparent Power Demand, Active Power Demand, Maximum Amp Demand, Maximum Apparent Power Demand and Maximum Active Power Demand. Easily see the parameters of your generator. Auxiliary Brake Control. Allows a safety brake to be used on generator. Touch Safe Power Terminals. Keeps fingers and people safe when inside the panel. ADTR Fuses. Quality time delay fuses, allow for very short term peeks in amperage. Fused Disconnect. Fused to eliminate the need for an additional disconnect, and ensure power is removed from panel when door is open. PLC Programmed and Tested Prior to Shipping. We build it we test it and make sure it works before you receive it. This saves time during local start up and commissioning. SEL Programmed and Tested Prior to Shipping. If you have not programmed one before you will be glad the work is done when you receive your panel. As Built drawings and component list. When panel is completed, as built drawings are supplied with panel as well as any and all component literature. Protection and Control Document. A document that you can provide to the utility so they can understand how the system operates. Accessory switches Inputs. Allows additional safety switches to be added to your generator. Induction Generation Basics. The induction generator is a device that converts mechanical energy into electrical energy. A grid tied induction generator also known as an asynchronous generator is a type of AC electrical generator that uses the principles of induction motors to produce electrical power. Any regular 3 phase AC asynchronous motor usually can be used as a generator without any internal modifications. Induction generators are most commonly used in applications such as pico, micro, and mini hydro power plants and wind turbines. When an induction motor is connected to an excitation source the utility it is capable of operating as a motor or as a generator. If the shaft is allowed to rotate at a speed below synchronous, the machine will attempt to operate as a motor. If the speed of the shaft is driven above 1. The prime mover e.
