CHAPTER 5: SETTINGS PRODUCT SETUPC70 CAPACITOR BANK PROTECTION AND CONTROL SYSTEM – INSTRUCTION MANUAL 5-595The per-unit base setting represents thousands, not single units. For example, a PU base of 1.000 is actually 1000 and aPU base of 0.001 is 1.When using RxGOOSE Analogs and PU base in FlexElements, the largest value that can be displayed in the FlexElementactual values is 2,140,000.000.ReportsNavigate to Settings > Product Setup > Communications > IEC 61850 > Reports.Figure 5-18: IEC 61850 buffered report panelAn IEC 61850 Report server is an efficient method for delivery of generic substation event information in a single server toa single client, such as a supervisory control IED. A Configurable Report is a UR element implementing an IEC 61850 Reportserver, either of the buffered or unbuffered kind. The following table lists the number of Configurable Report elements.Each Configurable Report element can report the values of up to 64 FlexLogic or FlexAnalog operands. Buffered reportelements queue value changes that occur while the client is offline and delivered when the client re-connects. Up to 512events can be queued. Unbuffered control blocks purge all value change events when the connection to the client is lost;any events that occur while the client is not connected are lost.Table 5-9: Number of report elementsConfigurable Reports interoperate with any client device of any manufacturer that conforms to the IEC 61850 edition 1.0or 2.0 report client requirements.The entities whose values are reported by a Configurable Report are known as members. The members are itemized in anordered list known as a data set. Each Configurable Report can use any one of the data sets provided that no more thanfour data sets are used for reports. This restriction is to limit the amount of processing power that can be allocated toreporting.Each enabled Configurable Report transmits an update to its client whenever a value change is detected in one or more ofits members. Also, the control block can be configured to send integrity reports containing the present value of allmembers either on demand from the client or periodically. A TCP handshaking mechanism causes messages that are notread and acknowledged by the client to be retransmitted.For a Configurable Report to operate, its members must be selected (that is, its data set configured) and a client must opena connection to, configure, and enable its report control block. Control blocks and data sets can be pre-configured bysending the C70 a CID file. See the UR Series Communications Guide for details. EnerVista UR Setup also can be used toselect the data set members and to pre-configure the control blocks.Each buffered report has the following settings.NumberBuffered reports 20Unbuffered reports 14
