Abstract

A power system plant includes a backplane arrangement including a primary and secondary bus to which intermediate power processing modules are selectively connected to the input and output power control and monitors of the plant. The backplane connections are controlled by the plug-in power processing modules. the resulting connections are unique to the type of plug-in module placeed on an input shelf (i.e. rectifier or converter plug-in module) and determine how the plant is to operated. The connections of these plug-in modules to the backplane connector are such that the plug-in module is designed to have its connectors connect to either primary or secondary referenced control signals. The connectors of the backplane accept both type of plug-in modules so that any plug-in module inserted is automatically connected to respond to the appropriate primary or secondary referenced control signals.

Claims

1. A power plant system, comprising:

a shelf including a backplane, the backplane having a pin receptacle connector, the pin receptacle connector having primary and secondary buses connected thereto;

a source of primary referenced control signals connected to the primary bus and a source of secondary referenced control signals connected to the secondary bus;

the pin receptacle connector also providing one or more modular plug-in locations, the shelf further disposed to receive plug-in power processing modules, each of said modules, when received, disposed to plug in to one of said plug-in locations;

each of said plug-in locations disposed to connect a module received therein to the primary and secondary buses in a first pinout arrangement if said received module is a rectifier; and

each of said plug-in locations further disposed to connect a module received therein to the primary and secondary buses in a second pinout arrangement if said received module is a converter.

2. The power plant system of claim 1, further comprising a monitor and control unit, said unit monitoring and controlling the source of primary referenced control signals and the source of secondary referenced control signals.

3. The power plant system of claim 2, further comprising a source of alarm referenced control signals, the source of alarm referenced control signals feeding, responsive to the monitor and control unit, the source of primary referenced control signals and the source of secondary referenced control signals.

4. The power plant system of claim 1, further comprising a source of alarm referenced control signals, the source of alarm referenced control signals feeding the source of primary referenced control signals and the source of secondary referenced control signals.

5. A method of distributing power control signals comprising the steps of:

providing one or more modular connectors to which power processing modules of differing types may be connected, each modular connector predesigned so as to present a first connector configuration when the power processing module connected thereto is of a first type, each modular connector further predesigned so as to present a second connector configuration when the power processing module connected thereto is of a second type;

feeding a primary bus with a supply of primary referenced signals and a secondary bus with a supply of secondary referenced signals;

connecting the primary bus and the secondary bus to the modular connectors, the first connector configuration permitting power processing modules of the first type to interface with primary referenced signals and secondary referenced signals according to a first mode, the second connector configuration permitting power processing modules of the second type to interface with primary referenced signals and secondary referenced signals according to a second mode.

6. The method of claim 5, in which power processing modules of the first type are rectifiers.

7. The method of claim 5, in which power processing modules of the first type are converters.

8. The method of claim 5, in which power processing modules of the first type are rectifiers and power processing modules of the second type are converters.

9. The method of claim 5, further comprising the step of:

monitoring and controlling the supply of primary referenced control signals and the supply of secondary referenced control signals.

10. The method of claim 9, further comprising the step of:

responsive to said monitoring and controlling step, feeding alarm referenced control signals to the supply of primary referenced control signals and the supply of secondary referenced control signals.

11. The method of claim 5, further comprising the step of:

feeding alarm referenced control signals to the supply of primary referenced control signals and the supply of secondary referenced control signals.
