Microprocessor controlled digital magnetic Excitation conditioning systems DERS-4W series
DERS-4W is a microprocessor-controlled digital self-encourage and magnetic control system, its
	high-performance voltage and current regulation of the disturbance can be made precise and rapid response, control accuracy <0.5 percent.With the industrial computer touch screen, it can show all kinds of real-time operating parameters and fault information, on-line modification to the system operating parameters.All functions  achieve by the corresponding software modules.
	
	Excitation system provides the following major software modules:
	
	- PID manner by the voltage regulator (Auto)
	- PI manner by the exciting current regulator (manual)
	- Reactive compensation (for poor areas ± 15%)
	- The most exciting current restrictions and protection
	- The most exciting current restrictions instantaneous
	- Low exciting restrictions and protection
	- the largest stator current restrictions and protection
	- V/Hz restrictions and protection
	- Constant power factor or constant reactive power adjustment (optional)
	- PSS functions(optional)
	- Soft-start exciting function,  smooth adjustment to prevent the generator voltage overshoot
	- Automatic tracking control
	- With over-current,  PT disconnected,  CT break,  misuse strong encouragement and misuse strong monitoring 
	and protection system
	- Fault records.
	- The watchdog function and self-inspection
	- On-line display and editing features
	- CAN network and a host computer communication
	- WINDOWS-based software and debug tools (optional)
