Abstract

Automatic procedures and manual procedures play important roles in the control of power plants. Their correctness is of great importance to the safe operation of power plants. Testing of such procedures is difficult, especially because of the problem of errors in specifications. By verifying high level specifications of automatic procedures and formalised specifications of manual procedures against an abstract plant model and a set of correctness requirements, this problem can be overcome to some extent. This paper describes the basic idea of such verification. It suggests using the verification approach as a complementary aid to traditional verification and validation which may involve different aspects including human factors.
