연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

The present invention provides systems and methods that allow for individual power sources to be disconnected and reconnected without interrupting the power supply from the other power sources and that allow for these power sources to provide power at substantially the same electrical parameters such as frequency, phase, and voltage.

The invention claimed is: 1. A method for supplying power to a load using multiple power sources, comprising: providing power comprising a first value of a parameter from a first power source to the load; monitoring the first value; providing power comprising a second value of the parameter from a second power source to the load, wherein the second value comprises substantially the first value when the first value is within a range of values for the parameter and is within the range when the first value is outside the range; disconnecting the first power source from the load when the first value is not within the range; and reconnecting the first power source to the load when the first value is within the range and while the second power source continues to provide power to the load. 2. The method of claim 1, wherein the parameter comprises frequency. 3. The method of claim 2, wherein the parameter comprises frequency and the first value comprises substantially 50 Hertz. 4. The method of claim 2, wherein the parameter comprises frequency and the first value comprises substantially 60 Hertz. 5. The method of claim 1, wherein the parameter is voltage. 6. The method of claim 1, wherein the parameter comprises phase. 7. The method of claim 1, further comprising storing the first value of the parameter. 8. The method of claim 7, wherein the step of storing the first value comprises storing the first value that comprises a last monitored first value that is within the range for the parameter. 9. The method of claim 1, further comprising the step of drifting a second value of the parameter to a fundamental value. 10. The method of claim 1, wherein providing power from a first power source to the load comprises providing power from a grid power source. 11. The method of claim 1, wherein providing power from a first power source to the load comprises providing power from one or more generators. 12. The method of claim 1, wherein the step of providing power from a second power source to the load comprises providing power from one or more generators. 13. The method of claim 12, wherein the step of providing power from one or more generators comprises providing power from one or more microturbines. 14. The method of claim 1, wherein the step of providing power from a second power source to the load comprises providing power from a grid power source. 15. The method of claim 1, wherein reconnecting the first power source to the load comprises drifting the second value of the parameter of the second power source towards the first value of the first power source when the first value becomes within the range while the second power source continues to provide power to the load and reconnecting the first power source to the toad when the first value and the second value are substantially the same. 16. A power distribution system, comprising: a load; a grid power source connected to the load which provides power having a grid frequency; a generator connected to the load which provides power having a generator frequency; a controller connected to the generator, wherein the controller comprises a default frequency generator which provides the generator with a default frequency to provide power when disconnected from the grid power source, wherein the controller is operative to provide the generator frequency to the generator and is operative to drift the generator frequency to the grid frequency; and a sensor connected to the grid power source and to the controller that measures a grid operating condition, wherein the grid operating condition comprises the grid frequency. 17. A power distribution system, comprising: a load; a grid power source connected to the load which provides power having a grid frequency; a generator connected to the load which provides power having a generator frequency; a controller connected to the generator, wherein the controller comprises a grid period stretcher that attempts to alter the generator frequency to detect islanding conditions, wherein the controller is operative to provide the generator frequency to the generator and is operative to drift the generator frequency to the grid frequency; and a sensor connected to the grid power source and to the controller that measures a grid operating condition, wherein the grid operating condition comprises the grid frequency. 18. A method for detecting whether a potential power source is still providing power to a load, comprising: providing power having a first frequency from a first power source to the load; providing power having a second frequency from a second power source to the load wherein the second frequency is substantially the same as the first frequency; attempting to drift the second frequency of the power from the second power source away from the first frequency of the power from the first power source; monitoring the second frequency of the power provided by the second power source; and evaluating whether the first power source is providing power to the load. 19. The method of claim 18, wherein providing power from a first power source comprises providing power from a utility grid. 20. The method of claim 18, wherein providing power from a second power source comprises providing power from one or more generators. 21. The method of claim 18 wherein attempting to drift the second frequency of the second power source away from the first frequency comprises attempting to lower the second frequency. 22. The method of claim 18, wherein attempting to drift the second frequency of the second power source away from the first frequency comprises attempting to raise the second frequency. 23. The method of claim 18, wherein evaluating whether the first power source is still providing power to the load comprises determining that the first power source is no longer providing power if the second frequency drifts away from the first frequency. 24. The system of claim 16, wherein the controller comprises: a mode switch logic device that is operative to disconnect and reconnect a power source based on input from range detectors; a frequency range detector that is connected to the mode switch logic device and which determines if the grid frequency is within a range of values; and a frequency adjust loop that is operative to drift the generator frequency to the grid frequency. 25. The system of claim 17, wherein the controller comprises: a mode switch logic device that is operative to disconnect and reconnect a power source based on input from range detectors; a frequency range detector that is connected to the mode switch logic device and which determines if the grid frequency is within a range of values; and a frequency adjust loop that is operative to drift the generator frequency to the grid frequency. 26. A power distribution system, comprising: a load; a grid power source connected to the load which provides power having a grid frequency; a generator connected to the load which provides power having a generator frequency; a controller connected to the generator, wherein the controller comprises a default frequency generator which provides the generator with a default frequency to provide power when disconnected from the grid power source, wherein the controller is operative to provide the generator frequency to the generator and is operative to drift the generator frequency to the grid frequency; and a sensor connected to the grid power source and to the controller that measures a grid operating condition, wherein the grid operating condition comprises a voltage of the grid power source. 27. The system of claim 26, wherein the controller is further operative to disconnect the grid power source from the load if a voltage of the grid power source is outside a range of values. 28. The system of claim 26, wherein the controller comprises a voltage range detector that is connected to a mode switch logic device, wherein the voltage range detector determines if the voltage is outside a range of values.
