The invention discloses a method for evaluating the power system static risk based on hybrid power flow. The method comprises the steps that (1) according to the current structure of a power system and a planning scheme, a corresponding planning scheme model is established; (2) according to equipment data and the structure of a power grid, predicated faults of the power grid and the possibility of the predicated faults are analyzed, and then a predicated fault set is established; (3) the power flow corresponding to all the faults in the predicated fault set is worked out through the risk state based on the hybrid power flow, and for the fault with power flow out of range, load loss is used as a fault consequence; (4) according to the load loss of the fault states and the possibility of the fault, the system risk indicator is worked out; (5) according to the system risk indicator, the weak link of the system is found. According to the method for evaluating the power system static risk based on the hybrid power flow, the problem that when high-order fault occurs in a large complicated power grid, misconvergence of power flow is caused due to the fact that only alternating-current power flow is applied during risk evaluation is solved through the hybrid power flow.

The invention discloses a power grid dispatching operation real-time risk assessment method with equipment aging factors considered. The method includes the steps that (1) the sequence of dispatching operation instructions to be operated is read, the dispatching operation states between the dispatching operation instructions in each step are determined, and meanwhile non-power information at the current moment is obtained, wherein the non-power information comprises the equipment operation information and the social state information; (2) expected fault scene sets of all the dispatching operation states are determined; (3) the real-time occurrence probability of each expected fault scene in the expected fault scene sets corresponding to all the dispatching operation states is calculated; (4) the load reduction quantity when the control expense for enabling the expected fault scenes to be recovered to a normal working state from a failure state is minimum is determined; (5) risk indexes under all the dispatching operation states are calculated; (6) risk control measures are formulated according to practical situations so as to guarantee normal execution of the sequence of the dispatching operation instructions, and the safe and stable operation capacity of power grids is improved easily.

The invention relates to an examination client anti-cheating screen locking method. The method comprises the following steps: (1) detecting the installation situation of an examination client; (2) installing the examination client; (3) opening examination paper by using the examination client; (4) examining a user and locking a screen; (5) judging whether the screen is switched by the user, namely discontinuously checking whether the current examination window is at the most front end by using an examination server, if the window is not at the most front end, activating the window immediately, maximizing the window and putting the window at the most front end; and (6) automatically closing the examination client after the examination is completed. According to the examination client anti-cheating screen locking method disclosed by the invention which can lock the examination shield of the user and prevent the user from cheating, and can be operated on a personal computer and controlled safely, the user can only see the examination paper of the user in the examination and cannot switch the window to examine other contents; the method is matched with enterprise network remote online training, and the fairness and the impartiality of the user in the examination are guaranteed.

The invention relates to the technical field of field operation risk analysis, in particular to a power enterprise field operation risk analysis method based on fault tree analysis. Aiming at the defect in the prior art that the risk evaluation to field operation of a power enterprise lacks scientific quantitative analysis, the invention provides the power enterprise field operation risk analysis method based on the fault tree analysis. According to the power enterprise field operation risk analysis method, a quantitative risk level EG.risk of the power enterprise field operation is obtained by adopting a fault tree analysis method and combining perennial monitoring and statistical data to various field operation activities of the power enterprise, and the defect of the prior art that the risk evaluation to field operation of the power enterprise lacks scientific quantitative analysis is overcome. The power enterprise field operation risk analysis method is concise in design, easy to implement, relatively low in maintenance and energy consumption cost and applicable to risk analysis of various complicated field operations and has broad application and popularization prospects.

The invention provides a risk test method for power gird dispatching operation. The risk test method for the power gird dispatching operation comprises the steps: receiving a current operation command conducted to target equipment and confirming risk state information; obtaining the number of nodes which are beyond a voltage boundary, overload number of branches, actual voltage amplitude value of each node which is beyond the voltage boundary and actual transmitting power of each overload branch under the states of failed operation, successful operation and successful operation development; obtaining load reduction quantity after failure and load reduction quantity under successful operation; obtaining real-time probabilities when operation succeeds and fails; obtaining real-time probability of failure after operation fails and real-time failure probability of the target equipment when operation succeeds; obtaining a risk indicator of the current operation; and sending an alarm out when the risk indicator is larger than or equal to a preset value. The invention further provides a risk test device for the power gird dispatching operation. The risk test device for the power gird dispatching operation is capable of pre-testing security status of a power gird caused by the power gird dispatching operation and guaranteeing the safe operation of an electrical power system.
