Furthermore, the controller can solve a lot of control-, measuring- and recording tasks all around the Petersencoil. Control methods As a standard feature, the regulator offers different methods for the automatic control of a Petersen-coil. Depending on the requirements, the REG-DP can control either to a percentage or absolute detuning-current or a given zero-sequence- voltage. It is remarkable, that during a ground-fault, the Petersen-coil can be corrected by the detuning and adjusted to the resonance point. Furthermore, there are different methods available for the control of several Petersencoils in the same network. Resistor control Included as an independent functional unit there is a resistor- control for the "increase of the residual ohmic current", which can be freely parameterised and which contains even a thermal model. Recording of the Zero-Sequence-Voltage An integrated electronic “recorder” continuously stores the time history of the zero-sequence-voltage and the coil-position. The chart-time lines can be shown and evaluated either on the display of the controller or on a PC. This integrated “net spy” enables to record and monitor long-term alterations of the zero-sequence voltage. The parameterisation-software WinREG can be used to evaluate and archive the recorded data. Connection to the SCADA system and REGSys The controller REG-DP is part of the control system REGSys and therefore it can be easily connected to the voltage regulator REG-D or to the multi-transducer MMU-D. An essential attribute of REGSys is, that all components, which are connected by the system-bus E-LAN, can be parameterised or connected to the supervisory control and data acquisition system ( SCADA ) over only one interface. For this reason, the measured values and parameters of all connected devices are available to the SCADA system and can be read out or modified there. Gateways according IEC 60870-5- 103 (VDEW) and IEC 60870-5-101 (balanced or unbalanced mode) are available. Multimaster-System-Architecture If several devices are connected via the system-bus E-LAN, each bus-node can be parameterised or read-out via interface (COM1, COM 2) of any other node by using a PC. In addition, several PC´s can access on different bus-nodes simultaneously.
