  This paper is devoted to study the circumstances favourable to detect
circumstellar and circumbinary planets in well detached binary-star-systems
using eclipse timing variations (ETVs). We investigated the dynamics of well
detached binary star systems with a star separation from 0.5 to 3~AU, to
determine the probability of the detection of such variations with ground based
telescopes and space telescopes (like former missions CoRoT and Kepler and
future space missions Plato, Tess and Cheops). For the chosen star separations
both dynamical configurations (circumstellar and circumbinary) may be
observable. We performed numerical simulations by using the full three-body
problem as dynamical model. The dynamical stability and the ETVs are
investigated by computing ETV maps for different masses of the secondary star
and the exoplanet (Earth, Neptune and Jupiter size). In addition we changed the
planet's and binary's eccentricities. We conclude that many amplitudes of ETVs
are large enough to detect exoplanets in binary star systems. As an
application, we prepared statistics of the catalogue of exoplanets in binary
star systems which we introduce in this article and compared the statistics
with our parameter-space which we used for our calculations. In addition to
these statistics of the catalogue we enlarged them by the investigation of well
detached binary star systems from several catalogues and discussed the
possibility of further candidates.
