Measurement (IO111 with 12 RTD sensors) Page 2

3 New system features and DIGSI 5 features with releases 7.50 and 7.30 DIGSI 5 Compatibility with Windows 10 Logging of security-relevant events IEC flexible engineering enhancements CFC Read access for protection settings News of V7.3 Copy and paste of function groups (FG), functions (FN) and function blocks (FB) Online monitoring of CFC charts chart-in-chart (sub-chart) write & access protection of charts Cross reference list New Hardware Line sensor for arc protection 1/6 on-site operation panel with 8 push buttons and LEDs Fault Recording Sequence of analog and binary traces within a fault record freely adaptable User changeable trace names Communications PROFINET IO support (complete data types) Simplified IEC GOOSE routing and flexible engineering Page 3

4 Read Access for settings in CFC Use setting as input for CFC plan Make settings visible in CFC signal list Settings SPG (bool), ING (integer), ASG (float) and ENG (enumeration) are included in signal list Settings used in CFC are marked in DIGSI View in CFC Online Test Page 4

5 SIPROTEC 5 Integrated Cyber Security Mutually authenticated and encrypted communication line between DIGSI 5 and the SIPROTEC 5 device Connection password handling according to BDEW White Paper, NERC-CIP, IEEE 1686, IEC Recording of security-relevant events and alarms over Syslog and in non-volatile security log in device Secure development Patch management Antivirus compatibility Confirmation codes for safety-critical operations (safety) Product hardening SIPROTEC 5 Independent testing Separation of process and management communication Crypto-chip for secure information storage and transmission Bay level Device uses key stored in crypto-chip to allow only firmware signed by Siemens to load Page 5

6 SIPROTEC 5 Integrated Cyber Security Highlight 1 Central logging of security-relevant events Highlight 2 Device-firmware is protected against manipulation Only firmware digitally signed by EM DG PRO can be loaded and processed This is ensured via an integrated crypto-chip with secured key storage and signature technology Page 6

7 SIPROTEC 5 Earth fault detection 80% of faults are earth faults Reliable detection essential in transmission and distribution Distribution grids 10/20/30/110kV Star point treatment often compensated Different methods with dedicated devices SIPROTEC 5 Watt metric Transient Harmonics Full parallel operation of different methods Increase of reliability Saving costs Saving engineering efforts All in One with SIPROTEC 5 Page 7

8 SIPROTEC 5 Earth fault detection All Advantages in one Device Transient function (digital) cos/sinϕ, 3I0>, U0>, admittance, Phi(U,I) Harmonics 3 rd, 5 th, 7th Pulse pattern Directional intermittend SIPROTEC 5 Combining advantages of several methods in one device Higher sensitivity 20 x compared to former algorithms Detection of High impedance / ohmic faults Very short ground faults Static faults Integrated solutions in SIPROTEC 5 reduces costs Elimination of operational 3I0 For closed rings and meshed networks Easy settings of the function Almost 4 years of positive field experiences Signalization of earth fault direction to control center using a priority scheme (user defined CFC) Page 8

9 SIPROTEC 5 Adaptive Protection Settings Remote control of protection settings through IEC Situation Calculation of protection settings & thermal limits for worst case conditions Restrictive limits are to high during >90% of the year Solution: Automatic adaption of protection settings Increased limits during >90% of the year Enhanced capacity of the transmission system without building new lines How is this done: Calculation of settings to be adapted on control center level Download of new settings to SIPROTEC protection relays using IEC grid transmission capacity Today s reserve due to fixed limits Grid capacity used today Control Center Page 9

10 Voltage Regulator From Single to Parallel Control Operation Requirement Voltage regulator for transformer parallel operation Protection and voltage regulation with one device Methods: Circulating current minimization or Master-Follower operation T11 OLTC T12 OLTC T13 IEC61850 Goose OLTC T14 OLTC Txx OLTC 7500A/1A 7500A/1A 7500A/1A 7500A/1A 7500A/1A QA11 QA21 QA31 QA41 QAx1 Solution SIPROTEC 5 voltage regulator function Master-Follower, circulating current and independent mode Interconnection between the devices via IEC Goose late binding (preconfigured data structures) Supports up to 8 transformer in parallel operation Page 10 Benefits QB11 QB12 B1 B2 QB21 QB22 QB31 QB32 QB41 QB42 Reduced investment (one device for protection and regulation) Easy parameterization with DIGSI and IEC system configurator Reduced wiring Faster commissioning QBx1 QBx2
