Monitoring of electrical grid infrastructure is a critical task carried out continuously by system operators to guarantee safe and reliable
operations. Traditional SCADA systems give operators a view of the system's operating conditions with a typical latency in the range of seconds and minutes.
</p>
<p class="bodyfont">
The relative low measurement frequency and low speed communications combined with the time required to execute analysis programs do not allow
SCADA systems to handle system emergency operations in real time. Decisions are made based on static power system models where a trade-off with accuracy is
generally needed.
</p>
<p class="bodyfont">
Communication and computing technologies available today allow monitoring functions with sub cycle resolution for power systems over large
geographical areas. The faster and higher resolution measurements introduced with synchrophasor technologies, also known as dynamic monitoring capabilities, enable
wide area monitoring at the system level based on accurate and precise data at high-speed data rates with extremely low latency, less than 200ms.
</p>
<p class="bodyfont">
When applied to wide area applications, typically executed at the operation center level, synchrophasors enable operators to optimize system
availability, reliability and stability analysis and operations. Phasor Data Concentrators (PDCs) and the Phasor Measurement Units (PMUs), that supply control
centers with phasor data, are key components of synchrophasor based wide area monitoring systems.

<p class="bodyfont"><strong>PRC-002-2 Dynamic Disturbance Recording (DDR)</strong></p>
<p class="bodyfont">
PRC-002 is a standard under development that will define the requirements for recording and reporting Sequence Of Events (SOE) data,
Fault Recording (FR) data, and Dynamic Disturbance Recording (DDR). The purpose of the standard is to facilitate analysis of disturbances.
</p>
<p> FR and SOE are features commonly available today in protection relays and SCADA equipment. </p>
<p class="bodyfont">
The third type of recording defined in the PRC-002-2 standard is DDR. Large interconnected systems can have inter-area
responses to each other resulting in slow oscillating load swings. These disturbances are characterized by oscillating power swings that can have
frequencies in the neighborhood of 0.1 to 4Hz, and duration in the range of a few seconds to minutes or hours.
</p>
<p class="bodyfont">
A dynamic disturbance recorder is a device cable of recording incidents that portray power system behavior during dynamic events such
as low frequency (0.1Hz - 4Hz) oscillations and abnormal frequency or voltage excursions.
</p>
<p class="bodyfont">
The advanced high capacity disturbance and event recording features available in the Multilin P30 Substation Phasor Data Concentrator
support the requirements of the PRC-002-2 standard and can significantly reduce the time needed for analysis and reporting of disturbance analysis and
regulatory reports.

Multilin P30 Built-in Historian Capabilities
</strong>
</p>
<p class="bodyfont">A typical GE substation Dynamic Disturbance Recording (DDR) system comprises of several PMUs reporting synchrophasor data at various different rates from 1 to 120 frames per second to a Multilin P30 PDC. Each of GE's Multilin PMUs may include 1 to 14 sets of phasor values (Multilin N60). Below are some typical examples of different types of PMUs with various combinations of phasor, analog and digital parameters. Large volumes of data generated by a DDR system requires a fast and reliable archiving method to guarantee data integrity for future analysis.</p>
<p class="bodyfont">The Multilin P30 PDC historian processor is a high capacity platform capable of recording up to 100.000 values per second.</p>

Local Archiving
</strong>
</p>
<p class="bodyfont">Distributed synchrophasor data storage through local archiving is recommended under the following two scenarios:</p>
<ul>
<li class="bodyfont">1. Upstream communication channels don't support the bandwidth to report all data monitored by the PDC.</li>
<li class="bodyfont">
2. Communication channels supports transmission of all data monitored by the Multilin P30 PDC. Archiving at the Substation level is <br>
introduced to increase system reliability and preserve monitored data in case of upstream channel communications failure.
