Phasor Generator - Technology
The Phasor Corporation generator (genset) has the following features.
1. Unique patented design (U. S, patents #6,815,934 and #7,330,016)
2. It is driven by a Diesel engine which has been converted to run on vegetable oil. Ideally, this oil can be produced from locally grown plants. The fuel is therefore sustainable and every bit as “solar” as solar panels. It simply uses a different solar process (photosynthesis as opposed to photovoltaics.) Besides the advantage of being a sustainable resource, vegetable oil has repeatedly been shown to be lower in overall emissions than petroleum Diesel fuel. In addition, the carbon dioxide absorption that occurs in oil producing plants during the photosynthetic process results in an overall neutral carbon dioxide cycle, with obvious important positive implications for the issue of global warning.
3. The generator itself is a three phase induction motor configured to run as an induction generator. The advantages of using an induction motor in this manner are as follows:
· Rugged, brushless design
· Manufactured in many countries and widely available
· Very efficient, particularly in the larger sizes
· Very scalable – available from several KW to hundreds or even thousands of KW
4. The generator can be operated in an AC mode but the preferred (and patented) configuration is to create a DC output voltage and use a DC to AC inverter for AC power. The advantages of this are as follows:
· Not limited to an engine speed of 1800 or 3600 RPM (for 60 Hz power). Allows the engine to run at a speed which can be optimized for power, emissions, and/or fuel economy.
· DC output results in the ability to store energy in batteries. For hybrid electric applications, battery storage dictates DC power. For grid tied applications, batteries enable operation as an uninterruptible power supply (UPS). For stand alone power generation, batteries enable UPS operation, while also allowing genset to be shut down during periods of low power demand, so genset doesn’t run in low power, inefficient range.
5. Grid tied operation is feasible with an approved inverter. (Conventional AC gensets cannot grid tie without additional control circuitry.)
6. Cogeneration capability - ability to use waste engine heat for useful purposes. The amount of useable waste heat is comparable in magnitude to the amount of electrical power produced, and this heat energy is easily transferred from the engine coolant to the intended application.
7. Microcontroller control system with the following advantages:
· Automatic control of voltage output, current output, battery charging, heating of vegetable oil, and other critical control variables.
· Ability to remotely start up or shut down genset and to monitor all critical parameters such as power output, fuel level, oil pressure, engine temperature, battery charge level, and fault detection.
· Ability to log all operating parameters for later analysis in spreadsheet or other database format.
· With internet connection, ability to start up or shut down genset remotely and monitor and diagnose the unit from anywhere in the world.
The vegetable oil conversion technology used in the Phasor Generator has been developed by the Elsbett Company of Thalmassing, Germany. For over three decades, Elsbett has been one the world leaders in Diesel engine technology, with hundreds of patents and significant innovations to their credit. Their vegetable oil conversion technology for Diesel engines is used in thousands of vehicles in Europe as well as in ships, locomotives and many other applications.
