Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To release overload of a system quickly by breaking noncritical loads having high increasing rate of electric energy sequentially until the generated electric energy is settled within an allowable range when a decision means makes a decision that the electric energy generated from a generator exceeds an allowable level. SOLUTION: Generators 1, 2 are linked through a bus link 15 and operated in parallel to critical loads 5, 6 and noncritical loads 7-12 with power. When the generator 1 or 2 is stopped due to a failure or when the load 5, 6, 7-12 increases, an overload is generated in the system. An analog input converter 27 is fed with the electric energy generated from the generators 1, 2 and the electric energy demanded by the noncritical loads 7-12. A decision section 33 in a CPU 31 compares the electric energy with a predetermined allowable level and makes a decision whether the system is overloaded or not. When overloaded, a load breaking section 34 commands a digital output converter 28 to break the load having high increasing rate of electric energy demand determined at an increasing rate operating section 32 thus releasing overload quickly.
