Protection Security Assessment (PSA) Siemens PSS SINCAL Protection Modules<\/h1>\n

Requirements and Use Cases of Siemens PSS SINCAL Protection Modules<\/strong><\/p>\n

The protection security assessment Siemens<\/a> PSS SINCAL Protection Modules has two functions: Protection analysis <\/strong>and Overcurrent time protection <\/strong>check.<\/p>\n

In meshed networks and in networks with a high penetration of distributed generation, the check of orderly function (selectivity, speed, dependability, security) of the network protection solely based on input data\/grading diagrams is often insufficient. In addition to observing specific fault events in the protection simulation, it is therefore necessary to check the protection settings of the entire network protection for all possible fault locations. While this must be done in a time-efficient manner, it is also necessary to identify weak points in the network protection reliable.<\/p>\n

The growing number of decentral energy resources (DER) with fluctuating power flow increases the number of switching operations in the network. From the point of view of network operation, this requires a quick check of the entire network protection (e.g. before each switching operation).<\/p>\n

A further requirement is to provide and document proof of the maximum permissible switch off times of the network protection regarding the thermal destruction of lines. If necessary, protection settings must be adjusted to prevent the thermal destruction of lines.<\/p>\n

Solution<\/strong><\/p>\n

The protection analysis (PSA) in Siemens<\/a> PSS SINCAL Protection Modules performs an automated check of the setting values of all protection systems present in the network by calculating fault events in the entire network. As a result, weak points in the network protection are visualized, allowing incorrect settings and faulty protection concepts to be detected.<\/p>\n
