Embodiment Construction

[0033] The present invention will be further described below in conjunction with the drawings. The following embodiments are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

[0034] Real-time power generation plan and its closed-loop control generally start the preparation of real-time power generation plan every 5 minutes. After the preparation of the plan, the unit power generation plan and optimized control mode are recommended to be sent to AGC for execution. The invention provides reasonable backup demand constraints for the optimization of the closed-loop control strategy of the real-time power generation plan according to the real-time grid operation conditions and future grid operation predictions, and adjusts the standby changes, power flow changes, and closed-loop control conditions during the real-time execution of the power generation plan and participation...

Abstract

The invention discloses a real-time generation schedule and a closed-loop control evaluation analysis method thereof. The closed-loop control evaluation analysis method is characterized by comprising the following steps: determining the real-time generation schedule and closed-loop control unit cluster classification; calculating a real-time generation schedule (CGS) regulating standby demand index; calculating a real-time generation schedule regulating standby adequacy index; calculating a power grid security monitoring index; calculating a real-time generation scheme closed-loop control depth index. The real-time generation schedule and the closed-loop control evaluation analysis key indicator and calculating method thereof are scientific and reasonable; the closed-loop control effect is objectively evaluated, and the tracking situation of the generation unit to the real-time scheme is analyzed online and immediately fed back, so as to form the more effective closed-loop control strategy, improve the real-time power grid running risk response capability, meanwhile reduce the manual intervention of scheduling operators and the frequently repeated regulating situation of a lot of units, prolong the service life of the generator unit, and improve the economic benefit of a power plant.

Description

Technical field [0001] The invention belongs to the field of power system dispatch automation, and relates to a real-time power generation plan and a closed-loop control evaluation and analysis method thereof. Background technique [0002] In recent years, the coordinated and rapid development of my country's UHV and all levels of power grids is gradually forming a super-large AC and DC power grid. As the power network becomes larger and larger, the operation of the power grid is becoming increasingly complex, and the pressure of peak and frequency regulation is increasing. The operation mode of different control target units changes frequently. To improve the control quality of automatic power generation control (AGC), it is necessary to rely on real-time power generation plan to perform three grid frequency adjustments according to the system load trend, adjust and track the power generation plan of the planned unit, avoid frequent adjustment of the unit and unreasonable allocat...
