Plant simulator
First Claim
1. A plant simulator comprising a plant simulation unit which simulates the behavior of a plant;
- a plant monitoring and operation unit which displays on a display screen parameters and the plant status computed by this plant simulation unit and, by using this display screen, gives the plant simulation unit the operation performed on the plant; and
a simulation instructing unit which, connected to a terminal screen, gives the plant simulation unit the setting of initial values necessary for simulation from this terminal screen and a demand instruction, which may be to demand discontinuation of the execution of simulation, the plant simulator simulating a system accident according to a control model and a plant model, further comprising;
a system accident factor database in which action logics of system accident factors matching the control model are stored;
a system accident factor selecting unit having a selecting device for taking out data stored in this system accident factor database; and
a system accident executing unit which executes a system accident on the basis of data taken out of the system accident factor selecting unit, whereby;
the system accident is simulated.

Abstract
A plant simulator which makes it possible to set factors which could invite a system accident and to simulate the process of occurrence of a system accident. The plant simulator has a plant monitoring and operation unit 300 which displays on a display screen parameters and the plant status computed by a plant simulation unit and, by using this display screen, gives the plant simulation unit the operation performed on the plant; and a simulation instructing unit 100 which, connected to a terminal screen, gives the plant simulation unit the setting of initial values necessary for simulation from this terminal screen and a demand instruction, which may be to demand discontinuation of the execution of simulation, the plant simulator simulating a system accident according to a control model and a plant model, further including a system accident factor database 504 in which action logics of system accident factors matching the control model are stored; a system accident factor selecting unit 500 having a selecting device for taking out data stored in this system accident factor database; and a system accident executing unit 400 which executes a system accident on the basis of data taken out of the system accident factor selecting unit, whereby the system accident is simulated.
