The invention discloses a test beam long-term loading system and method. The loading system comprises a lever, a tension bar, a distributive beam, a counterweight device, a hydraulic pressure weight adjusting device, a ground anchor and a force transmission and testing device; the design of a loading system is carried out using the lever principle, firstly based on the test requirements, the size of the applied load as required is set; after the determination of the size of the load, the length ratio of the short arm and the long arm of the lever is designed from the size of the test site, the size of the loading lever and other aspects, under the precondition that the weight of the lever is not taken into consideration; in theory, the larger is the length ratio of the short arm and the long arm of the lever, the larger is the weight applied to the force bearing point of the long arm, and the larger is the amplifying multiple of the load at the force bearing point of the lever, and the aim of applying relatively large load is further achieved by utilizing relatively small weight. The long-term loading system is easy to operate, the loading and unloading save time and labor, the performance is stable, and long-term testing is guaranteed. The long-term loading system in the later period does not require special maintenance, and basically is not affected by external conditions.

A distributed new energy full-observation modeling method and system based on topology automatic aggregation of the present invention extracts new energy grid-connected information based on distributed new energy grid-connected ledgers, and builds a distributed energy grid-connected database; based on the obtained The topology model of the main distribution network establishes the mapping relationship of the main distribution network and fits the integrated grid topology model of the main distribution network; through grid-connected information and sites or distribution transformers of the integrated grid topology model, one-to-one or many-to-one Mapping; based on the connection relationship between the built new energy and the main distribution network integration model, build a topological connectivity map of power grid equipment; set the observation points of the full observation model, and build a new energy automatic aggregation full observation that reflects the mapping relationship between each observation point and new energy Model.

For the characteristics that a middle-discharging type cement raw material mill system is provided with two control loops of a coarse powder bin and a fine powder bin, the coupling action exists between the coarse powder bin and the fine powder bin and the load of the two bins needs to be coordinated and optimized, the invention adopts a double-layer-structure predication control method with two layers of optimization and control to carry out independent optimization and control on a control system. A steady optimization layer realizes the load optimization on the coarse powder bin and the fine powder bin according to the economic optimization index; a dynamic control layer selects milling noise and the negative pressure of an inlet of the fine powder bin as output variables, selects the feeding amount and the openness of a distributing valve as input variables, and selects the rotating speed of a powder selecting machine as a feed-forward variable so as to form a two-input two-output one-feed-forward multi-variable predication control system. The double-layer-structure predication control method has the advantages that the total load level of a raw material mill is effectively improved, the mutual coupling action when the coarse powder bin and the fine powder bin are respectively controlled is avoided, the influence of lagging of the feeding amount is reduced, the disturbance action of quality adjustment on a product on the control system is inhibited, the automation degree is improved, the yield of raw materials is increased, the continuous operation rate of the control system is increased and the economic benefit is increased for enterprises.

The invention discloses a construction method of an arch filler of a two-way curved arch bridge; the arch filler is divided into a plurality of casting sections in the longitudinal direction of a bridge; a support template is mounted at the casting tail end of each casting section; concrete casting construction is performed on the initial casting section of the bridge in the longitudinal directionof the bridge; a support template at the tail end of the casting section is removed after the concrete of the initial casting section is initially set; concrete casting construction of the next casting section is performed; a support template at the tail end of the casting section is removed after concrete of the next casting section is initially set till the casting construction of all the casting sections is completed. The two-way curved arch bridge is reinforced and maintained by reducing the self weight of the arch filler, the load grade, the traveling comfort and the structural durability can be improved, the construction is simple and convenient, the quality is controllable, the bridge maintaining cost is reduced, and the reinforcing and maintaining effect is remarkable. The bridgeappearance is not changed, and the construction method has significance for reinforcing and maintaining the two-way curved arch bridge with cultural relics quality and historical value.
