heat network. F i g u r e 13 shows how the
new district-heat storage unit has been integrated
into the district-heat generation
facilities of the GKM plant.
Unit 9 is currently under construction and
will go on line in 2015. Ta b l e 3 shows
a selection of technical data of the GKM
heat storage system. The construction activities
began in September 2012 (F i g u r e
14). The system is scheduled to operate as
planned by fall 2013.
The GKM district-heat storage unit will fulfil
two major functions:
– securing the district-heat supply in the
event of a failure of the other districtheat
supply systems, and
– provide for cost-efficient operational optimisation
of the CHP units in the GKM
plant.
Summary
Owing to the rapid increase in the capacities
of plants based on the use of renewable
energy for heat and power generation,
the demand for energy storage systems in
Germany and Europe is high and will continue
to grow. The paper at hand takes a
closer look at large-scale systems installed
for the purpose of heat and energy storage
in heat and power generation plants. The
basic principles of energy storage systems
are described by a number of example systems
and are complemented by an overview
of the state of applications and their
respective implementation. For reasons of
an enhancement of the energy efficiency
of plants, it continues to be advisable to
operate combined heat and power units
(CHP). However, since situations are expected
to be on the rise where the amount
of power and heat produced does not coincide
with the power and heat demand
(e.g. in heat and power generation plants),
it will be of paramount importance to find
optimised technical solutions. One of the
options in this respect are systems where
heat is stored in large-sized storage units.
Water is commonly used as a medium for
storing heat. Furthermore, there are large
systems where liquid salts or solid matter
are used. The use of water/steam in largescale
applications, however, is normally
limited to temperatures below 300 °C because
of technical and commercial factors.
The systems most frequently used are nonpressurized
systems or systems that operate
with a minor overpressure. The GKM
heat storage system has been presented as
an example of how a large heat storage unit
can be integrated into a CHP plant and a
large district-heat network. There is an obvious
demand for further advancement of
the energy storage concepts for high temperature
levels.

The present VGB-Standard “Electric Generating Unit Protection“ was newly compiled by the VGB
project group of the same name. It continues the “Guidelines for electric generating unit protection”
issued by the VDEW in 1985, and integrates new possibilities and requirements with the application
of multi-functional digital protection devices.
Due to the adaptation to new norms and guidelines a new edition became necessary.
The VGB-work group “Electrical machines and plants” appointed the project group “generating
unit protection”, compiled of experts of European power station operators. After the completion
of a preliminary draft, this was discussed with manufacturers of protection devices and then
jointly revised.
