Embodiment Construction

[0046] The power flow automatic integration and adjustment method of the present invention first integrates the power flow data according to a preset scheme, and then automatically adjusts the power flow data according to predetermined operation limit constraints and adjustment principles and methods until the power flow results meet the operation constraints.

[0047] The present invention mainly includes two parts, one part is the automatic integration of power flow data, which is responsible for integrating and supplementing various plan data, network topology data, and reference power flow data to form complete power flow data; the other part is the automatic adjustment of power flow data, which is responsible for Check and adjust the balance of power flow data active load and generator active output; check and adjust voltage limit, and allocate reactive power reasonably to obtain power flow that meets operating constraints.

[0048] 1. Trend automatic integration

Abstract

The invention provides a flow data integrating and flow adjusting method, which is used for developing and planning the research and the attempt of checking data integration and flow adjustment based on the actual power network data. In the method, the network topology data and the planning data are integrated into the flow data, and the deleted data is extracted from the referential flow data so as to form the integral flow. The flow adjustment provides a practical method, the flow program is not modified in the method, the analysis is performed by adopting the result calculated by the flow; therefore, the method automatically realizes the flow balance with work or idle work, automatically adjusts overstep voltage and obtains the flow to meet the operation requirements. Moreover, the method provides initial values for the safe stability analysis and the auxiliary decision-making next, facilitates customizing a reasonable daily scheduling, and enhances security and stability of the power network.

Description

technical field [0001] The invention relates to the field of safety and stability assessment of electric power systems, in particular to an automatic integration and adjustment method of power flow data for plan checking. Background technique [0002] Plan checking is to evaluate the safety and stability of the planned operation mode at a certain point or points in the future, and it is necessary to perform power flow and stability calculations on the operation mode data at this point. Since planning data is not complete power flow data, data integration and adjustment are required to form a convergent power flow that meets operational requirements. Therefore, tidal current data integration and tidal current adjustment are the basis of the whole plan checking work. The integration of power flow data analyzes and supplements various planning data and network topology data, and integrates them to form complete power flow data. The power flow adjustment calculates and adjusts...
