In
the focus: Dispatchable generation for flexibility in the energy
system
To
optimally integrate volatile renewable energies such as wind and
photovoltaics into the energy system, a high degree of system
flexibility is required. This flexibility is mainly provided by the
options grids, storage technologies and sector coupling
technologies, demand-side-integration as well as dispatchable
generation. At present dispatchable generation is the major option.
VGB PowerTech presents on its topic page "Flexibility" related
publications, studies and standards with know-how and expert
knowledge. These provide comprehensive practical information on
optimised technical and economic plant deployment and operation.

VGB
PowerTech: Technical competence centre for wind power at the NRW
booth of HUSUM Wind 2019
VGB
PowerTech presents its objectives at the NRW booth of the HUSUM Wind
2019. VGB’s mission is to support the co-operation on all technical
topics and tasks for wind power plants. The focus points are the
exchange and transfer of experiences and infor-mation in VGB
committees, standardisation (best practice), and the representation
of interests of wind power plant owners in several User Groups. The
experiences pave the way for VGB-Standards for build and operation
of power plants.

Condition
monitoring of wind turbines, Part II: SCADA-based condition
monitoring
Three-step process of
CMS-data utilization for
condition-based maintenance In
the VGB research project 383 Condition Monitoring Systems of Wind
Power Plants: Status Quo, User Experience, Recommendations, Part I,
a study was carried out to identify the state of the art and main
challenges related to the use of CMS for wind turbines.
The
challenges can be summarized as follows:
- Sensor
reliability and accuracy.
- Limited
fault-detection performance (false alarms, missed faults).
- Purely
subjective prognosis of remaining useful life.
Conventional
Condition Monitoring Systems require a certain amount of sensors. An
additional approach is based on Supervisory Control and Data
Acquisition (SCADA) signals. It has the advantage of utilizing
existing data acquisitions. Published literature states SCADA
signals in a temporal resolution of 1 Hz have considerably higher
information content than 10min-averaged SCADA data. But through
statistical distribution, the 10 min data can be extrapolated to
higher resolutions as 1 Hz data leading to a representative
estimation. This extrapolation as well as the use of SCADA signals
as a CMS is the main focus of part II of this project (no. 421).

A
new edition of the KKS Pocketbook is available! – Free compact
information about the KKS
The
"KKS Pocketbook" (2nd revised and extended edition 2019) is an
abridged version (extract) of the publication
VGB-S-811-01-2018-01-EN “KKS – Identification System for Power
Stations” (formerly VGB-B 105e). The handy 128-page brochure
supports the decoding of KKS codes, KKS is one of the world's most
widely used key systems for the designation of equipment and
components in power generation. The abridged version is to assist
the user in decoding systems, components and documents employing KKS
codes at the plant. This summary contains the: Function Key;
Equipment Unit Key and Component Key for plants of the supply of
energy (conventional, nuclear and renewables).

VGB-S-170-12-2018-08-EN
- Measures for the avoidance and handling of instrumentation and
control equipment failures – Now available as eBook!
The
former VGB Guideline VGB-R 170 A1e “Measures for the avoidance and
handling of instrumentation and control equipment failures” was used
since 2005 supporting specification and assessment of control and
instrumentation systems with regard to their robustness against
failures against the background of increased use of standard IT
components and IT networks.
The
Technical Committee “Electrical Engineering and I&C” as
responsible commit-tee, had to decide if this guideline shall
further have validity, whether it should be recommended for use and
to what extent, if necessary, a revision must be made. As a result
of the examination, the content use and the validity of the
application was fully confirmed. Only the issue information security
(IT security) resulted in the need in adjustments arising from new
regulations in laws and related regulations.
