Abstract

The invention relates to an LCC direct current power transmission simulation system and a field layer equipment simulation device. The LCC direct current power transmission simulation system comprises a simulation device and a real-time digital simulator. The field layer equipment simulation device comprises an industrial control computer, a field bus card and a data collection card, wherein the field bus card is inserted in the industrial control computer and is used for information interaction with a control protection device to be detected; the data collection card is inserted in the industrial control computer and is used for information interaction with the real-time digital simulator; and the field bus card is connected with the data collection card through a PCI bus. The LCC direct current power transmission simulation system and the field layer equipment simulation device take a general industrial control computer and a PCI board card as a hardware platform and contain a plurality of data communication modes, so that the flexibility of the system is improved; simulation of the LCC direct current power transmission filed layer equipment for different factories and different technical routes can be realized; accurate simulation of the filed layer equipment is realized; and the performance of the LCC direct current power transmission system can be detected more comprehensively.

Description

technical field [0001] The invention relates to an LCC type direct current transmission simulation system and a field layer equipment simulation device, belonging to the simulation field of LCC type direct current transmission. Background technique [0002] Domestic LCC-type DC transmission real-time simulation systems usually use RealTimeDigitalSimulator (RTDS) to simulate the AC-DC primary system, and form a closed-loop system with the DC control and protection system. way. [0003] In the LCC type direct current transmission system, before the control and protection equipment of the LCC type direct current transmission system is shipped to the actual site, the system simulation test must be carried out in advance in the production plant, and the field layer equipment is used to connect with the control and protection equipment to detect the control and protection equipment performance. Due to the intensive technology of the LCC DC transmission system and too many field-...
