Embodiment 1

[0045] Embodiment 1 provides a DC system simulation operation evaluation system, the system includes:

[0046] The standard answer processing module is used to establish a standard operation module library. The teacher extracts modules from the standard operation module library to establish an evaluation main line. The evaluation main line is an official standard process composed of standard operation modules;

[0047] The simulation operation evaluation module is used to construct a synthetic standard answer based on the evaluation main line and in combination with the simulation operation process of the simulation operator, compare the simulation operation record with the synthetic standard answer, and perform simulation operation evaluation;

[0048] The evaluation result processing module is used to form evaluation records according to the comparison results, calculate evaluation results, and form a performance report.

[0049] In Embodiment 1, the DC system simulation ope...

Embodiment 2

[0061] In Embodiment 2, a DC system simulation operation evaluation system is provided, such as figure 2 As shown, the DC simulation operation evaluation system mainly includes four modules: simulation record processing, standard answer processing, simulation operation evaluation and evaluation result processing.

[0062] (1) Simulation record processing: A text record file is formed during the simulation operation of the DC system, referred to as the simulation record for short. The simulation record file completely records the effective click positions of the left and right mouse buttons of the simulation operator during the simulation operation, the text input by the manual keyboard during the special operation, and also records the operating condition information of the simulation system, such as system variables. Bit (converter transformer tap, AC filter switching), system alarm information (equipment status alarm, protection action information, power change information)...

Abstract

The invention provides a simulation operation evaluation method and system of a direct current system, and belongs to the technical field of direct current power transmission system simulation. The method comprises: based on the standard operation module library, establishing a simulation operation standard process as an evaluation main line; according to the evaluation main line, establishing and synthesizing a standard answer in combination with a simulation operation process of a simulation operator; comparing the simulation operation record with the synthesized standard answer, and performing simulation operation evaluation; and forming an evaluation record according to a comparison result, calculating an evaluation score and forming a score report. Direct-current simulation operation and disordered simulation operation of a sequential operation process can be accurately judged, strict operation processes can be comprehensively compared, a clear precedence order of each operation module (or step) is determined, and for a disordered operation process comprising two or more operation modules (or step), the invention has complete accuracy, and avoids the phenomena of misjudgment and missed judgment.

Description

technical field [0001] The invention relates to the technical field of direct current transmission system simulation, in particular to a simulation operation evaluation method and system of a direct current system. Background technique [0002] The DC system refers to the DC transmission system, including the rectification side converter station, the inverter side converter station and the transmission line. Regardless of the rectification or inverter side, the converter station includes converter valves, converter transformers, DC field equipment, AC field equipment, bipolar public grounding pole equipment, etc. Its main task is to achieve long-distance by converting AC power into DC power. Transmission, and then into alternating current for the user to use.
