摘要： PURPOSE:To easily recognize a power flow route by a method wherein the color of a connection display element arranged at a place where a bus displayed on a power flow diagram and symbolized for every voltage class by a single lines is connected to system constituent apparatus such as a transformer, a transmission line or the like is made identical to that of the bus. CONSTITUTION:The connection state of the following is represented by colors of connection display elements DU1 to DU30: system constituent apparatuses such as transformers Tr1 to Tr7, transmission lines Tl1 to Tl8 and the like which are displayed on a power flow diagram; and buses which are represented by single-line symbols BUS1 to BUS6 for every voltage class such as e.g. 275kV or 154kV. The colors of the connection display elements DU1 to DU30 are determined to be different for the individual buses to be connected. When a breaker and a disconnecting switch are turned on and off, they are displayed by the colors of the buses which are connected electrically. Thereby, the visual recognition property of the connection state is not deteriorated in the power flow diagram of a large-scale power system, and it is possible to easily recognize the route in which a power flow flows.

摘要： PURPOSE:To apply the stability decision system of a power system to a main protection fault, in which system configuration after a fault is eliminated controls stability, by using the quantity of unbalance between generators of deceleration force displaying the difference of stability by system configuration after the fault is eliminated as a stability index and computing and deciding stability in details when the quantity of unbalance exceeds a threshold. CONSTITUTION:Current system information is collected at a step S1, and the state of a power flow is computed at a step S2. A large number of assumed disturbance f1, f2,...fn are set at a step S3, transient stability up to a moment when a fault is eliminated is calculated at a step S4, and outputs from each generator before the fault is generated and in a moment when the fault is eliminated are acquired. DP values to each assumed disturbance are computed on the basis of these results and the inertial constants of each generator at a step S5, the DP values and a threshold DP* are compared at a step S6, and instability is decided temporarily to the assumed disturbance when the DP values are larger than the threshold DP*. Transient stability is calculated at a step S7, and stability is decided in details.
