The invention provides a tide deduction sandbox simulation system. The system comprises a deduction strategy formulation module, a deduction execution module, a quick element operation auxiliary module, a mode evaluation module, a misconvergence automatic analysis module, a power grid sandbox display module, a data acquisition module and an automatic sandbox establishing module, wherein the deduction execution module is respectively connected with the deduction strategy formulation module, the quick element operation auxiliary module, the misconvergence automatic analysis module and the mode evaluation module; and the mode evaluation module is sequentially connected with the power grid sandbox display module, the automatic sandbox establishing module and the data acquisition module. The system helps and guides an operation dispatcher to adjust a tide mode and is tightly interacted with an operator, the operating suggestion is given, the system change is intuitive and visual, the adjustment process can be automated, and the tide adjustment efficiency in the process of calculating an operation mode is greatly improved.
