Title: System and method for controlling power output of a power source

Description:
TECHNICAL FIELD 
     The present disclosure relates to a power source, and more particularly relates to systems and methods for controlling a power output of the power source. 
     BACKGROUND 
     Power sources, such as a generator set and a hydraulic pump set are generally used for generation of electric power and irrigation of a land and crops, respectively. Such a power source includes an engine and a power conversion device, such as a generator or a hydraulic pump, to generate electric power or hydraulic power, respectively. The power sources are generally installed at a worksite to serve the purpose of the applications. The power source also typically generates a rated power output. However, a maximum power output of the power source may change based on a given ambient condition. Further, the maximum power output may be less than the rated power output. In such a case, an operator may have to visit the worksite to de-rate the power output of the power source to the maximum power output for optimal performance of the power source. However, de-rating the power output of the power source manually based on the ambient condition of the power source is a time consuming process. Further, operator skill is required for manually controlling the power output of the power source. 
     JP Patent Publication Number 2008-267351 (the &#39;351 publication) discloses a method and a system for monitoring a power generating system capable of increasing the evaluation precision of the performance of an engine provided in a power generating device, and exactly predicting a failure and a deterioration status which is changed in a long time sequence. According to the &#39;351 publication, a plurality of predetermined engine intake air temperature ranges are set and a correlation of an allowable fuel consumption rate range to a power generation output is set at each of the intake air temperature ranges. An operation data average value is calculated by extracting the operation data existing in the engine intake air temperature range and the predetermined power generation output range.

     The first control module  126  is further configured to determine a final power output ‘P 3 ’ based on the first power output ‘P 1 ’ and the second power output ‘P 2 ’. Specifically, the first power output ‘P 1 ’ and the second power output ‘P 2 ’ are compared to each other and a minimum value of the first power output ‘P 1 ’ and the second power output ‘P 2 ’ is determined as the final power output ‘P 3 ’. 
     The controller  124  is further configured to compare the final power output ‘P 3 ’ with a predetermined power output ‘P 0 ’ of the engine  104 . In an example, the final power output ‘P 3 ’ may correspond to an optimum power output of the engine  104  for optimal electric power generation from the generator set  102  based on one of the ambient condition of the generator set  102  and the operating parameter of the engine  104 . The predetermined power output ‘P 0 ’ may correspond to a maximum rated power output of the engine  104 . The maximum rated power output of the engine  104  may be predetermined based on the ambient condition of the generator set  102  and the operating parameters of the engine  104 . Further, the predetermined power output ‘P 0 ’ may be stored in the memory associated with the first control module  126 . 
     In an embodiment, the controller  124  is configured to determine a ratio between the final power output ‘P 3 ’ and the predetermined power output ‘P 0 ’. The controller  124  further determines a final de-rate value ‘D’ based on the ratio between the final power output ‘P 3 ’ and the predetermined power output ‘P 0 ’. In other embodiments, the controller  124  may be configured to output the final de-rate value ‘D’ based on another relationship between the final power output ‘P 3 ’ and the predetermined power output ‘P 0 ’ stored in the controller  124 . 
     In another embodiment, the controller  124  may be configured to determine a first de-rate value based on the first power output ‘P 1 ’ and the predetermined power output ‘P 0 ’ of the engine  104 . The first de-rate value may be determined based on a first relationship between the first power output ‘P 1 ’ and the predetermined power output ‘P 0 ’.

The first de-rate value and the second de-rate value may be compared each other and a minimum value of the first de-rate value and the second de-rate value may be determined as the final de-rate value ‘D’. 
     The controller  124  is further configured to control the generator  106  to regulate a power output ‘P 5 ’ of the generator set  102  based on the comparison between the final power output ‘P 3 ’ and the predetermined power output ‘P 0 ’. In the illustrated embodiment, the second control module  128  is configured to control the generator  106  to regulate the generator set  102  based on the final de-rate value TY. A command signal ‘S 4 ’ indicative of the final de-rate value ‘D’ may be communicated to the generator  106  for regulating the power output ‘P 5 ’ of the generator set  102 . In an example, a plurality of generator sets may be coupled in parallel connection to share the external load.

Further, the generator set  102  may be connected or disconnected from the external load via the switch gear based on the final de-rate value TY. In another embodiment, the power output ‘P 5 ’ of the generator set  102  may be uprated if a value of the final de-rate value ‘D’ is greater than one. 
     In an embodiment, the second control module  128  may determine a current power output ‘P 4 ’ of the generator set  102 . The current power output ‘P 4 ’ of the generator set  102  may be further communicated with the first control module  126  to determine a current load acting on the engine  104 . 
     In an embodiment, a service kit  130  may be connected to one or more inlet-outlet ports disposed in the control panel to communicate with the controller  124 . The service kit  130  may be carried by an operator to the location of the generator set  102  at predefined intervals. The service kit  130  may be further used for reading various input and output values related to operation of the engine  104  and the generator  106 . The service kit  130  may be further used for resetting the first predetermined relationship and the second predetermined relationship stored in the controller  124 . Thus, the final de-rate value ‘D’ may be optimally varied based on the ambient condition of the generator set  102  and the operating parameter of the engine  104 . 
     In an embodiment, the controller  124  is further configured to limit a rate of change of the power output ‘P 5 ’ of the generator set  102  based on a predetermined rate limit. The predetermined rate limit may be defined between an up-rate limit and a de-rate limit. The up-rate and de-rate limits may be defined to limit the rate of change of the power output ‘P 5 ’ to prevent any abrupt change of the power output ‘P 5 ’ in a given period of time. An unexpected change of the power output ‘P 5 ’ may occur due to malfunction in the first sensor module  120 , the second sensor module  122 , or unexpected change in ambient condition of the generator set  102 , the operating parameter of the engine  104  or the generator  106 . In an example, the rate of change of the power output ‘P 5 ’ may take place linearly or nonlinearly within the predetermined rate limit.

The faction of the final power output ‘P 3 ’ may further correspond to the ratio between the final power output ‘P 3 ’ and the predetermined power output ‘P 0 ’. In various embodiments, the fraction of the final power output ‘P 3 ’ may be determined based on the predetermined power output ‘P 0 ’ of the engine  104  based on a predefined mathematical relationship between the final power output ‘P 3 ’ and the predetermined power output ‘P 0 ’ of the engine  104 . The fraction of the final power output ‘P 3 ’ may be further subtracted from unity to determine the final de-rate value ‘D’. The final de-rate value ‘D’ is further communicated with the second control module  128  to control the generator  106  and hence to regulate the power output ‘P 5 ’ of the generator set  102 .

The ambient temperature ‘S 1 ’ and the ambient pressure ‘S 2 ’ are compared with the first predetermined relationship to determine the first power output ‘P 1 ’. Similarly, the inlet manifold air temperature ‘S 3 ’ is compared with the second predetermined relationship to determine the second power output ‘P 2 ’. 
     At step  406 , the method  400  includes determining the final power output ‘P 3 ’ based on the first power output ‘P 1 ’ and the second power output ‘P 2 ’. The controller  124  compares the first power output ‘P 1 ’ and the second power output ‘P 2 ’ and determines the minimum value of the first power output ‘P 1 ’ and the second power output ‘P 2 ’ as the final power output ‘P 3 ’. 
     At step  408 , the method  400  includes comparing the final power output ‘P 3 ’ with the predetermined power output ‘P 0 ’ of the engine  104 . The first control module  126  compares the final power output ‘P 3 ’ with the predetermined power output ‘P 0 ’ of the engine  104 . In another embodiment, the second control module  128  in communication with the generator  106  may determine the current power output ‘P 4 ’ of the generator set  102  and communicate the current power output ‘P 4 ’ with the first control module  126 . The controller  124  may determine the current load acting on the engine  104  based on the current power output ‘P 4 ’ of the generator set  102 . 
     At step  410 , the method  400  includes controlling the generator  106  to regulate the power output ‘P 5 ’ of the generator set  102  based on the comparison between the final power output ‘P 3 ’ and the predetermined power output ‘P 0 ’ of the engine  104 . In an embodiment, the final de-rate value ‘D’ determined based on the ratio between the final power output ‘P 3 ’ and the predetermined power output ‘P 0 ’ is communicated to the generator  106  to regulate the power output ‘P 5 ’ of the generator set  102 . In another embodiment, the first de-rate value determined based on the first power output ‘P 1 ’ and the second de-rate value determined based on the second power output ‘P 2 ’ are compared to determine the final de-rate value ‘D’. 
     Thus the control system  100  determines final de-rate value ‘D’ based on the ambient condition of the generator set and the operating parameter of the engine  104  to regulate the power output of the generator set. Hence, the operator may not be required to visit the location of the generator set  102  and manually de-rate the power output ‘P 5 ’ of the generator set  102  based on the ambient condition of the generator set  102 . Further, the generator set  102  may be controlled to generate optimal power output to increase life of the generator set  102 .
