Method and apparatus for producing silicon thin rods

The invention relates to a method and to a device for producing thin silicon rods such as those used in the conventional Siemens process for precipitating silicon. Due to the strongly increasing demand for silicon for semiconductors and solar cells, the demand for thin silicon rods is also increasing. The method according to the invention fundamentally corresponds to the classical pedestal method. According to the invention, the induction coil (1) used comprises further draw openings (5.1, 5.2, 5.3, 5.4) about the central opening (4) having circumfluent current. A sufficiently uniform temperature profile is generated in the stock rod under the induction coil (1), such that the point of the stock rod melts and a melt pool forms (6.1) (6). One thin silicon rod (9.1, 9.2, 9.3, 9.4) each can be drawn upward out of the melt pool through the further draw openings in the induction coil. In contrast to the known prior art, no rod is drawn upward through the central opening having circumfluent current. The further additional draw openings are preferably disposed concentrically to the central opening and at a sufficient distance from the outer edge of the stock rod (6). The spacing thereof to each other is selected such that the growing thin silicon rods do not thermally influence each other too strongly, so that the individual thin silicon rods grow as uniformly as possible. The greater the diameter of the raw Si rod, the greater the diameter of the induction coil can be selected, and a correspondingly greater number of additional draw openings can be provided.

Power system source-grid-load interaction control strategy evaluation method

The invention relates to a power system source-grid-load interaction control strategy evaluation method comprising the following steps: acquiring power information and natural power characteristics of a power source side, a grid side and a load side of a power system, analyzing the interaction behavior characteristic of power equipment, and establishing a power system interaction resource structure; analyzing the response characteristics of interaction resources to electricity price, incentive and scheduling interaction mechanisms, and establishing power variation curves of the interaction resources under different interaction mechanisms; determining the interaction potential of the interaction resources, and establishing an interaction cost variation curve of the interaction resources within the scope of interaction potential; determining the amount of interaction of the interaction resources under the three interaction mechanisms, selecting an interaction strategy combination which meets the demand of system power balancing and minimizes the total cost of interaction, and obtaining an interaction control scheme; and evaluating the interaction control scheme respectively from the aspects of response characteristic, effect of interaction, grid security and grid economy, and comprehensively evaluating the influence of the source-grid-load interaction control strategy to the grid and the interaction efficiency of the strategy. The limitation of single index is overcome.
