A RTDS (Real Time Digital Simulation System) comprises N pieces of parallel GTNET boards; a process layer switch is respectively connected with a security and stability control system and the N pieces of parallel GTNET boards through a cable; the GTNET boards transmit SV analog quantity and GOOSE switch quantity signals output by the RTDS to the security and stability control system through the process layer switch, wherein N is greater than 1; and GOOSE trip outlet signals output by the security and stability control system are transmitted to the GTNET boards of the RTDS through the process layer switch. According to the digital closed-loop test system for the stability control system provided by theinvention, the analog quantity and switch quantity acquisition and trip signal outlets of the stability control system are achieved through VLAN setting and a digital interface communication configuration file of a router, so that a complete digital closed-loop test system of the stability control system is formed; and full digitalization of input and output of the stability control test system is realized, and the efficiency and reliability of stability control policy verification can be improved.

The invention discloses an IPC communication method based on a shared memory pool. The method comprises the steps: carrying out the IPC communication, which comprises message receiving and message sending; wherein the message sending comprises the steps of applying for a shared memory, continuing if the application succeeds, otherwise ending; writing message data into the shared memory; convertingthe applied virtual address of the shared memory into a logic address; sending the logic address to a destination receiving queue; message receiving of the receiving queue comprises the steps that the receiving message queue receives the logic address; restoring the logic address into a memory pool ID and a shared memory minimum management unit logic address according to a conversion formula; obtaining a virtual address through the memory pool ID logic address, wherein the sum of the virtual address and the shared memory minimum management unit logic address is equal to the actual storage address of the message; processing the message; releasing the logic address; memory pool creation management. According to the method provided by the invention, the information copying times of the kernel during IPC communication are reduced. The system overhead is reduced.

The invention provides a blade mate-balance method, blades and a wind driven generator. The method is applied to the wind driven generator. The wind driven generator comprises the blades of different gravity torques, weights and gravity centers. Each blade comprises a blade root position counterweight point, a blade middle position counterweight point and a blade tip position counterweight point. The method specifically comprises the steps that with the blade of the highest gravity torque as the standard, the other blades are subjected to gravity torque mate-balance by adding balancing weights on the different position counterweight points of the other blades; and after the other blades are subjected to gravity torque mate-balance, with the blade of the highest weight as the standard, mate-balance is carried out on the weights and gravity centers of the other blades. In this way, the blade mate-balance method is flexible and diverse, and the technical problem that as the gravity centers of blades shift too much, the service life of an existing wind driven generator is short can be solved.

The present invention provides a method of configuring a map style through the Lua. According to the method, a map is rendered in a hierarchical manner; each map layer is symbolization for geometric elements; and the same geometric element has different rendering styles in different layers.
