ABSTRACT:
FIELD OF THE INVENTION
This invention relates to power system plants in which intermediate power processing modules are mounted in a housing structure of a power plant and between input and output power access modules of that plant; and in particular to a backplane bus structure providing a particular control structure for accepting and controlling different types of inserted power processing modules.
BACKGROUND OF THE INVENTION
Power plant systems, having input and output power access with intermediate power processors are usually designed with a particular control structure and with anticipated operation using only one type of intermediate plug-in processor. The overall plant structure is usually limited to one type of control and is not readily changeable to use plug-in power processors of the other type control and power output and hence can not accommodate differing plug-in power processing modules.
SUMMARY OF THE INVENTION
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 of the plug-in intermediate power processing modules are unique to the type of plug-in module placed on an input shelf (i.e. rectifier or converter plug-in module) and how the plant is to be 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.
The power plant system includes control signal generators and signal references for the primary bus and the secondary bus. The backplane connectors of the plug-in module are designed to connect through the appropriate bus to one or the other of these control signal sources. Its backplane connectors also connect to one or the other of the primary or secondary busses to receive alarm return referenced control signals. The power plant system operates in a rectifier or converter plant mode determined by signal interconnections made within the backplane of the system.
The completed backplance connections for the rectifiers and converters are unique from one another although the connection receptacles are the same regardless of application.
