Excitation input power is normally supplied from the excitation transformer connected with generator output terminals or supplied from a permanent magnet generator (PMG). Some case, excitation input power may be supplied from external utility. Excitation output power of HDEC2000 unit is supplied to excitation winding of main machine or exciter machine after rectification and smoothing process through power module (switching IGBT) controlled by regulation output signal (PWM duty) of HDEC2000 unit’s software function block.
Control Power
No external control power is normally required for HDEC2000 unit since the control power is internally supplied from excitation input power. For few special application, either ac or dc power source may be supplied externally. Control power is used as driving power of each component in the HDEC2000 unit. See appendix C (Specification) for more detail information.
Sensing Input and Auxiliary Input
The voltage and current sensing signals for HDEC2000 unit are measured from sensing transformer installed on generator or generator external cubicle. Both of single phase or three phase voltage sensing configuration is supported by HDEC2000 unit. In case of current sensing system, single phase sensing is available and cross current loop sensing is also available. Excitation voltage and excitation current signals are sensed by measuring device installed internally.
For remote control application via analogue signal, +/-10Vdc or 4 …20mA signal is available and the
HDEC200 unit also provides.
Digital Input and Output
Most of control Tasks such as Excitation ON/OFF, Auto/Manual and Setpoint Adjust are achieved via digital input signal. The HDEC2000 unit provides seven digital inputs for predefined functions and three digital inputs for programmable functions. Digital inputs can be controlled with dry contactor or PLC open collector signal. The HDEC2000 unit provides three programmable output relays and one watchdog relay also.
Communications
Three communication ports are provided for initial configuration in the factory (or commissioning in site), for data exchange between HDEC2000 units for redundant system and for purpose of remote access. The communication ports consist of RS232 (COM0), CAN (COM1) and RS485 (COM2) ports.
User Interface
The HDEC2000 unit provides two kinds of user interface devices which consist of front panel LCD display and key pad (buttons). Most of operating information such as analogue signals, fault events are displayed on the LCD display panel. A few of setup functions are supported via front panel keypad. The upgrade for key pad function (configuration of essential parameter) and monitoring function (display of more various parameters) are planed later.
The Configuration and monitoring software for HDEC2000 unit called HDCM is connected through RS232 communication port on the front panel. The HDCM software provides very useful functions such as parameter configuration, setpoint adjustment, control gain estimation and real time measurement for factory setup and site commissioning.
