The invention discloses a real-time running status evaluation based power distribution network running risk warning system. The system comprises a power grid model and running mode acquisition module, a risk warning analysis module, a risk solution module and an analysis result display module, the power grid model and running mode acquisition module is used for acquiring a power grid model and a running mode from a power distribution network SCADA (supervisory control and data acquisition) system; the risk warning analysis module is used for analyzing risks of the power distribution network according to the current power distribution network model and the running mode; the risk solution module is used for analyzing solution strategies for the power distribution network risks to obtain a power distribution network risk solution strategy; the analysis result display module is used for displaying a power distribution network risk analysis result and a power distribution network risk solution strategy analysis result. The power grid model and the on-line power grid running mode are synchronized in real time from the power distribution network SCADA system, and real-time performance of risk analysis is guaranteed; rich risk warning display means are provided, and users are assisted to quickly position a risky area; the risks of the power distribution network are analyzed from the perspective of the power grid running mode, advance discovering and timely processing are achieved, and power supply reliability of the power distribution network is improved.
