4 The key to reliable grid quality Siemens range of products for grid and power quality optimization comprises digital fault recorders and phasor measurement units (PMUs), metering devices, transponders, and grid quality recorders. Digital fault recorders and PMUs make it possible to safely and quickly detect weaknesses and problems within a grid. They comprise a large number of functions, such as fault recording, voltage and frequency recording, system quality recording, report and alarm generation, as well as network diagnosis and fault location. Precise consumption data analysis of all components connected to the system enable economical operation, thus also increasing system efficiency. Devices for grid quality recording continuously document all relevant parameters. Problems can be precisely identified, localized, and solved at an early state. Improvement Measurement Definition of measures Data transmission Stable grid quality requires a continuous monitoring circle Reporting and archiving Analysis Always a handle on power quality One of the main points in maintaining grid quality is the minimization of system interruptions. The faster a failure can be analyzed and the more clearly possible faults can be identified, the shorter the interruption durations. Contract penalties can be limited or even prevented. The growing share of renewable energy within the grids has led to the increasing importance of power quality, which is increasingly becoming a competitive factor. This is why grid quality is an integral part of technical risk management, requiring measuring devices and applications that acquire, record, and analyze all required data. Intelligent, innovative technologies from Siemens provide grid operators and utilities with efficient and economical answers to these challenges. The SIMEAS, SENTRON, and SICAM PQS product families ensure precise asset monitoring, which enables maintenance in line with demand. Intelligent information and communication structures ensure speed and transparency when it comes to deviations from predefined grid quality parameters. All relevant information can automatically be aggregated to a grid event, and corresponding reports and alarms can be generated. Users are immediately informed online, via text message, , printout, or fax, so they can react without delay and in a coordinated manner

5 Integration ensures availability A modern automation system provides a high degree of functionality and flexibility, including comprehensive options for telecontrol, communication, and the connection of peripherals. Siemens continually drives innovation for the benefit of its customers. The consistent implementation of international standards is a perfect example of that. Network and IT functions, its interoperable system structure, and the integration into existing systems are characteristics of SICAM. Clear advantages, such as easy configuration, faster commissioning, and efficient operation ensure an economic investment. SICAM combines classical telecontrol functionality and substation automation. The engineering system TOOLBOX II makes engineering for SICAM 1703 and SICAM PAS highly comfortable.
