摘要:
A control system is provided for load sharing between a plurality of compressors (8, 34). The control system determines the actual coefficients of export flow for the compressors (CEFactual1, CEFactual2), compares the actual coefficients of export flow with a common or individual coefficients of export flow setpoints (CEF SP) generated by one or more central controllers (48, 50), and then generates control signals for adjusting the operating points of the compressors in order to load balance the compressors.
摘要:
A floating master controller system is provided that includes a plurality of hardware units, each capable of carrying out at least one mechanical function. Each hardware unit includes a processor configured via controller code included in a memory to cause the respective hardware unit to operate and carry out the at least one mechanical function. The controller code for each hardware unit includes a master controller (MC) application and at least one floating master controller (FMC) application. Each MC application is operably configured to function as an active master controller that controls the at least one mechanical function in each of the plurality of hardware units in the system and is operably configured to control the at least one mechanical function for its respective hardware unit responsive to tracking another one of the MC applications that is functioning as the active master controller in the system. Also, the at least one FMC application for each hardware unit is operably configured to automatically coordinate with each other FMC application to move active master controller functionality for the system between each of the different MC applications in the system.
